In a statement, the group's political bureau accused Israel of carrying out the attack which killed senior Hamas official Saleh Al-Arouri.
Israel has denied responsibility for the attack with Mark Regev, the senior advisor to the Prime Minister Benjamin Netanyahi, telling NBC News that Israel had "no comment" on Tuesday's events in Beirut.
In their statement, the Houthis described Arouri's killing as a "brutal and cowardly crime."
The group described Arouri as a "leader" of Palestinian resistance, expressing support for avenging action to be taken against Israel.
More background: The Houthis and Hamas share a backer in the Iranian government, which widely suspected of providing extensive assistance to both groups.

Hamas political leader calls "cowardly assassination" of Saleh Al-Arouri a "terrorist act"
From CNN's Jonny Hallam
Ismail Haniyeh, the political leader of Hamas, mourned the death of senior Hamas official Saleh al-Arouri, calling the attack in Lebanon a "terrorist act."
In a televised speech, Haniyeh condemned Arouri's killing as a "cowardly assassination" and blamed Israel for the deadly strike.
Haniyeh also mourned the deaths of two leaders from Hamas' military wing, the Qassam Brigades, Samir Findi Abu Amer and Azzam Al-Aqraa Abu Ammar, who were killed in the same strike.
Despite the assassinations, Haniyeh said Hamas would never be defeated.
"A movement whose leaders and founders fall as martyrs for the dignity of our people and our nation will never be defeated," Haniyeh said.
Israel has not confirmed it was behind Tuesday's deadly attack in Dahieh, a southern suburb of the Lebanese capital.
"Israel has not taken responsibility for this attack," Mark Regev, a senior advisor to Israeli Prime Minister Bejamin Netanyahu said in an interview with MSNBC. "But whoever did it must be clear that this was not an attack on the Lebanese state. It was not an attack even on Hezbollah."

The US State Department on Tuesday rejected comments by far-right Israeli officials —Finance Minister Bezalel Smotrich and National Security Minister Itamar Ben Gvir — calling for the resettlement of Gazans outside of Gaza, denouncing them as "inflammatory and irresponsible."
"We have been told repeatedly and consistently by the Government of Israel, including by the Prime Minister, that such statements do not reflect the policy of the Israeli government. They should stop immediately," State Department spokesperson Matt Miller said in a statement.
Miller noted in the statement that the department has been "clear, consistent, and unequivocal that Gaza is Palestinian land and will remain Palestinian land, with Hamas no longer in control of its future and with no terror groups able to threaten Israel."
"That is the future we seek, in the interests of Israelis and Palestinians, the surrounding region, and the world," he said.
The State Department’s comments come after Israeli cabinet ministers in Prime Minister Benjamin Netanyahu's right-wing coalition made remarks advocating for the resettlement of Palestinians outside of Gaza.
On Sunday, Smotrich, called for Palestinian residents to leave the Gaza strip, making way for Israelis who could "make the desert bloom," according to Reuters.
Ben Gvir expressed support for resettling Palestinians from the Gaza Strip abroad, declaring that the war presents an “opportunity to concentrate on encouraging the migration of the residents of Gaza” during a political meeting.

Israeli finance minister claims all of Israel’s enemies will "perish"
From CNN's Lauren Izso and Tara John
In a seemingly a veiled reference to the killing of a senior Hamas leader on Tuesday, Israeli finance minister Bezalel Smotrich wrote on his official social media platforms that all of Israel’s enemies will “perish.”
His comment comes after Hamas said Tuesday that one of its senior officials had been killed in an attack in southern Beirut. Saleh Al-Arouri was a prominent Palestinian political and military leader whom Israel considers one of the key founders of the Al-Qassam Brigades, Hamas' military wing, in the occupied West Bank.

Israeli military spokesperson skirts question on death of senior Hamas leader in Lebanon
From CNN’s Sugam Pokharel
Israeli military spokesperson Daniel Hagari skirted a question from a reporter on the death of senior Hamas leader Saleh al-Arouri in an alleged Israeli strike in Beirut on Tuesday.
“We are focused on fighting against Hamas,” Hagari said, responding to the question during his daily press briefing. “The IDF is in a very high state of readiness in all arenas, in defense and offense. We are highly prepared for any scenario,” Hagari said.
His remarks came after Hamas said Tuesday that Arouri — one of its senior officials — had been killed in an attack in southern Beirut that it blamed on a "treacherous Zionist airstrike." Arouri was a prominent Palestinian political and military leader whom Israel considers one of the key founders of the Al-Qassam Brigades, Hamas' military wing, in the occupied West Bank.
“We are focused on the war against Hamas. There is terrorist activity by Hamas in different arenas,” Hagari said when asked what Israel knows about the nature of “weapons that Hamas has in Lebanon.”

Netanyahu adviser says Israel has "not taken responsibility" for attack on Hamas official in Lebanon
From CNN's Niamh Kennedy in Dublin
Israel had "not taken responsibility" for the attack that killed a senior Hamas figure in Lebanon, a top official said Tuesday.
During an interview with MSNBC, Mark Regev, who is a senior adviser to Israeli Prime Minister Benjamin Netanyahu, said he had "seen the reports" about the attack which killed senior Hamas official, Saleh Al-Arouri.
"Israel has not taken responsibility for this attack. But whoever did it must be clear that this was not an attack on the Lebanese state. It was not an attack even on Hezbollah," Regev said. "Whoever did this did a surgical strike against the Hamas leadership."
Regev said that although individuals who kill Israelis "can expect the Israeli state and the Israeli armed forces to ultimately reach them," this rather is a "general statement" of Israel's policy. "It's got nothing to do with this current situation, this specific situation in Beirut which I have no comment on," Regev said.
It is "very clear" that whoever had masterminded the attack "has a gripe with Hamas" itself, he added.

Blast in Beirut risks triggering a wider war

A blown-out building in the Lebanese capital flashed on local TV channels as plumes of black smoke billowed into the sky.
The Israeli military has not yet responded to CNN’s request for comment on the reports. If true, Arouri would be the most senior Hamas official killed by Israeli forces since the start of the war sparked by the October 7 Hamas attack on Israel.
In addition to dealing a blow to Hamas’ leadership, the apparent attack also risks further broadening the arena of the Israel-Hamas conflict.
It would mark the biggest Israeli strike on the Lebanese capital since the 2006 war between the two countries.
The apparent strike hit a popular neighborhood in Beirut’s southern suburbs, which are also a stronghold of Iran-backed Hezbollah. It reportedly struck a Hamas office, killing Arouri — one of the founders of the group’s military wing — during a meeting.
Lebanese Prime Minister Najib Mikati called it a “new Israeli crime that aims to drag Lebanon into a new phrase in confrontations,” referring to the ongoing, months-long tit-for-tat conflict between Hezbollah and Israeli forces in the Lebanon-Israel border region.
For nearly three months, the fighting has largely stayed within a roughly four-kilometer range of the border region, with Hezbollah striking Israel while Israel struck Lebanon.
It seemed to teeter on the precipice of a full-scale war between Israel and the Middle East’s most powerful paramilitary, Hezbollah, but fell short of sparking the conflict that the United States and other Western countries feared.
That may have changed on Tuesday afternoon, as the rules of engagement seemed to suddenly shift with the blast in Beirut.
During a televised address last summer, Hezbollah chief Hassan Nasrallah warned against Israeli assassinations in Lebanon, saying that they would inspire a “strong response” from the militant group.
"Any attack on Lebanese territories no matter the nationality or the faction (of those targeted) … will definitely trigger a strong response,” said Nasrallah in an August 2023 speech, adding that the group would try to prevent Lebanon from becoming an “arena for assassinations," invoking the country’s tumultuous past.In two speeches delivered since October 7, Nasrallah repeatedly raised the specter of an all-out war with Israel.
The speeches were fiery, but ultimately seemed to suggest that Hezbollah was intent on restricting their fight to the border area.
The fighting has since intensified and Israeli officials have threatened to ramp up their attacks on Hezbollah. Hezbollah has not yet released a statement about Tuesday’s incident, and it has not responded to CNN’s request for comment.
Nasrallah is expected to deliver a televised address on Wednesday in a speech that was scheduled last month. Observers will be watching it closely for signs of escalation.
“Nasser Kanani, the spokesman of the Ministry of Foreign Affairs, strongly condemned the false act of the Zionist regime in the assassination of Sheikh Saleh al-Arouri, the deputy leader of the Hamas movement and a faithful commander of the resistance, and two of the commanders of the Qassam Brigades in Beirut,” the statement said. “By committing such a crime, the criminal Zionist regime has once again shown its baseless foundation is built on terror and crime.”
Earlier Tuesday, a former Israeli ambassador to the United Nations, Danny Danon, congratulated the Israeli security and intelligence agencies for the assassination of the senior Hamas figure in Beirut. Danon is a senior member of the Likud party. “I congratulate the IDF, the Shin Bet, the Mossad, and the security forces for killing senior Hamas official Salah al-Aaruri (sp) in Beirut,” Danon said on X.
The Israel Defense Forces (IDF) said it didn't have a comment about the Hamas official being killed when reached out by CNN.

"Dreams have been shattered." Displaced Palestinians describe fear, death and disease as war rages into 2024
From CNN's Sana Noor Haq
Mohammed Aghaalkurdi says his nephews and nieces in Gaza are “craving a warm and healthy dinner” this year, as hundreds of thousands of displaced Palestinians try to seek protection from Israel’s bombardment and ground offensive.
“While children all around the world are celebrating Christmas and New Year’s and setting resolutions for what is hoped to be a bright future, children of Gaza are being heavily attacked,” Mohammed Aghaalkurdi, a program officer with UK-based charity Medical Aid for Palestinians (MAP), said Monday.
Aghaalkurdi’s testimony was shared with CNN by MAP. He’s staying in a rented house in Khan Younis, in southern Gaza, with at least 10 other people – including five of his colleagues and their families.
Israel’s complete siege on the Palestinian territory and severe restrictions of essential supplies entering the strip have triggered spiraling food prices, leaving 2.2 million residents in Gaza at risk of severe dehydration, malnutrition and infectious diseases including upper respiratory tract infections, diarrhea, lice and scabies, chickenpox, skin rash, jaundice and meningitis, according to the World Health Organization.
Israeli attacks on Gaza since Hamas’ October 7 attacks have killed at least 22,185 Palestinians, most of whom are women, children and the elderly, according to the Hamas-run Ministry of Health. CNN is unable to independently confirm the figures provided by the health ministry in Gaza due to restricted access to the region and the difficulty in verifying accurate numbers amidst the ongoing war.
“For more than 80 days, they (children) have been unmercifully killed and displaced with their families for countless times until (they) ended up in a helpless and cold tent, unprotected, hungry and thirsty,” said Aghaalkurdi.
“Their beautiful dreams have been shattered and turned into nightmares filled with fear and homelessness. Surrounded by exhausted and busy adults (looking for food and drinking water), our kids have lost the beautiful meanings of life,” he added.
“Despite what has been happening, there is a little hope we carry inside our hearts that calm will prevail soon and our kids will heal.”
Salwa Tibi, a displaced aid worker who works at the humanitarian agency CARE International, told CNN on Tuesday she hopes 2024 will bring “security, safety, peace and prosperity.”
Tibi, 53, is staying in a rented house in Rafah, in southern Gaza, with at least 20 relatives including eight children and babies – the youngest of whom is three months old.
“(I) hope Gaza will be reconstructed as quickly as possible, and that life will return to normal despite the severe pain, losses of loved ones, friends and relatives,” she said.
