Al-Shabaab threatens "another bloodbath" in Kenya

Garissa, Kenya CNN  — 

Kenya’s Interior Ministry named Mohamed Mohamud as the organizer of the attack. The senior Al-Shabaab leader is also known by the aliases Dulyadin and Gamadhere, it said.

Al-Shabaab, an al Qaeda-linked militant group based in Somalia, took responsibility for the attack, according to the U.S. Embassy in Nairobi.

Mohamud is “credited with having an extensive terrorist network within Kenya,” according to a Kenyan ministry document given to CNN.

The ministry offered a reward of 20 million Kenyan shillings, or about $215,000, for information on his whereabouts.

“We appeal to anyone with any info on #Gamadhere to share with relevant authorities and security agencies,” the Interior Ministry posted on Twitter.

Mohamud is in charge of external operations against Kenya, the document says, and he is the regional commander within Al-Shabaab in charge of the Juba region. In this role, he commands the militia along the border and “is responsible for cross-border incursions in the country.”

Mohamud’s network extends within the Dadaab refugee camp, the document says. Dadaab is the world’s biggest refugee camp, home to thousands of people, according to the United Nations. It’s in Kenya’s North Eastern Province near Somalia.

Mohamud has claimed responsibility for several attacks in the past few years, including December’s attack on a quarry in a Kenyan village near the Somali border, which killed at least 36 people.

Mohamud is Kenyan and has three wives and three siblings, including two with links to Al-Shabaab, the document says.

On Sunday, Kenya’s Interior Ministry identified another terrorist involved in the Garissa University College attack as Abdirahim Abdullahi.

Abdullahi’s father, Abdullahi Daqare, a government chief in Mandera in northern Kenya, told CNN that his son was missing.

Daqare is a Kenyan Somali, he said.

His son graduated in 2013 from Nairobi University law school and worked for a bank for two months before he went missing, Daqare said in a phone interview.

“I have received reports from people who found information (on) the Internet that my son was one of the terrorists,” Daqare said. “I previously told the government that the son is missing. I sought their help to find the whereabouts of my son.”

He added that the two had not been in contact since his son disappeared. Daqare said he had “really given up on him.”

On Sunday, families of some of the more than 147 people slain at Garissa University College left a mortuary in Nairobi after identifying the bodies of their loved ones.

One woman almost had to be carried out.

“Why? Why? Where are you, my children?” she wailed.

Across Garissa, there was a sense of fear, foreboding and grief.

The news agency Reuters videotaped a man holding his daughter’s hand at a church as military patrols and security officials searched people. A church member told the agency, “Nowhere is safe, but here in church you can come, you be with God and then you just console yourself.”

Horrific stories of survival and tales of massive loss continue to emerge.

To survive Al-Shabaab militants blazing through her dorm, shooting and killing classmates, 19-year-old Cynthia Cheroitich went into a closet, covering herself with clothes. Her two roommates hid under their beds. The gunmen called them out.

“(The gunmen) told them if you don’t know to read to them in the Muslim word, whatever, and then you lie down,” Cheroitich told CNN. “And then, if you know, you go to the other side.”

The 19-year-old student at Kenya’s Garissa University College didn’t see what happened next, but she heard more than enough.

“They were shooting everywhere,” she said. “I didn’t want to open my eyes.”

For the next two days, Cheroitich didn’t budge. Unable to get to water, she hydrated by drinking body lotion. When police went into her room – well after the carnage was done, with 147 dead at the school – she didn’t believe them. Only a visit by the head of the university convinced her that, finally, it was safe to come out.

Three days of national mourning for victims of the attack, declared by Kenyan President Uhuru Kenyatta, began Sunday.

Al-Shabaab threatens ‘another bloodbath’ in Kenya

Garissa is a town about 90 miles from the Somali border.

It is all due to Al-Shabaab, the Islamist extremist group that is based in Somalia but hasn’t confined its terrorism to there – as evidenced by Thursday’s university attack and the 2013 siege of Nairobi’s upscale Westgate Mall.

Saturday, the terrorist group warned that more carnage is coming as it promised “another bloodbath” in Kenya.

The threat drew a sharp response from Nadif Jama, the governor of Garissa county.

“The fallacy and satanic mindset of Al-Shabaab is that in Somalia, they kill Muslims and Somalis,” Jama said. “They cross the border here and then say they are killing non-Muslims. That is a tricky way of doing business.”

Jama said the militants were “bent on nothing but destruction” and aimed to sow division between Muslims and non-Muslims.

“But that is something we need to fight,” Jama said.

Gruesome parade

Police in Garissa on Saturday paraded the bodies of men they said had carried out the attack.

The corpses – locked in a macabre embrace and partially wrapped in an orange tarp – were piled on the back of a pickup truck and driven to a primary school soccer pitch for viewing.

A large crowd gathered, despite the baking sun and foul stench.

The truck drove up next to the onlookers, so that they could inspect the bodies.

Anger seethed in the crowd.

“These gunmen, they killed innocent children. We want to burn these people,” one man told CNN.

Presidents blasts Kenyans who help Al-Shabaab

Kenyan President Uhuru Kenyatta also had some harsh words Saturday for Al-Shabaab, as well as any those who supported them.

In a nationally televised speech, Kenyatta said the nation’s fight against terrorism “has been made all the more difficult by the fact that the planners and the financiers of this brutality are deeply embedded in our communities and were seen previously as ordinary, harmless people.”

Kenyatta condemned “corruption of the worst and most criminal kind (when) Kenyans … finance, hide and recruit on behalf of Al-Shabaab.”

“There is no form of legal penalty, social shaming and godly condemnation that they do not deserve, to the fullest extent,” the President said.

Describing Al-Shabaab as an “existential threat to our republic,” Kenyatta urged his fellow Kenyans to “tell those that believe a caliphate is possible in Kenya that we are one indivisible, sovereign and democratic state.”

“That fight will never change,” he added. “Our forefathers bled and died for this nation. And we will do everything to defend our way of life.”

Kenyatta declared three days of national mourning for the victims of the attack.
