Kyiv, Ukraine CNN  — 

Russian President Vladimir Putin claimed the war in Ukraine is “going according to plan” Thursday, with residents of the key city of Mariupol facing a deteriorating humanitarian situation, as the city remains under siege by Russian forces determined to tighten their grip on Ukraine’s south.

“The special military operation in Ukraine is going according to plan, in strict accordance with the schedule,” Putin said in his Security Council broadcast on state television, using the euphemism the Kremlin uses to describe the invasion of Ukraine. “All tasks are being successfully being carried out.”

His remarks came as civilians in Mariupol were trapped without power, heating or water.

France also gave a chilling warning that the “worst is yet to come” for Ukraine, following talks between Putin and his French counterpart Emmanuel Macron.

Mariupol authorities warned of a “critical” situation for residents amid heavy shelling. It’s not clear how many of Mariupol’s roughly 400,000 inhabitants have been able to evacuate the strategically important port city or how many have been killed or injured.

The Russian assault on Mariupol comes as its forces also fight for control of the Black Sea city of Kherson. The mayor of Kherson indicated overnight that Russian forces had seized control of the city of about 300,000, although claims remain disputed.

The advance in Ukraine’s south shows Russian forces are attempting to create the beginning of a potential land bridge that could link the port city of Odessa in the west, through Kherson and Mariupol to the separatist-held pro-Moscow territories in the east.

Mariupol’s deputy mayor Sergei Orlov told CNN’s “New Day” the southeastern city was now “surrounded” by Russian forces and was in desperate need of military and humanitarian aid.

“Our Ukrainian army and National Guard is very brave, they stand and fight for Ukraine, for Mariupol. But the situation is quite critical,” Orlov said Thursday.

“We are asking for help, for military help, and we are waiting for military help,” Orlov said. “Our internal forces are very brave, but we are surrounded by the Russian army, which has more people in their army.”

Following a 90-minute phone call Thursday between Putin and Macron, an Elysee source told reporters that Putin had said he intended to continue his military operation.

“Without making a prediction, we should expect the worst is yet to come. The (French) President said so yesterday as well. There is nothing in what Putin said today that should reassure us,” the source said.

Putin told Macron he was available for negotiations but emphasized that discussion must take place on the grounds of neutralization and disarmament of Ukraine, the source said.

The Russian leader also said that if Kyiv wanted to talk, it must act now – and if Ukrainians don’t accept these conditions, he will obtain the same result by the military path, the source said. Putin denied having bombarded Kyiv and warned that the situation would worsen, but that it was the fault of Ukraine, the source said.

France estimates that Russia’s military ambition is to take all of Ukraine, the source added.

Mayor: Russians creating a ‘humanitarian catastrophe’

Orlov warned that Mariupol was facing a humanitarian crisis after what he said had been 26 hours of continued shelling.

“They are destroying our city with all weapons, from artillery, from airplane bombing, from tactical rockets, from multiple launch rocket systems,” Orlov said.

“We do not have electricity in the whole city, we do not have water supplies, we do not have sanitary systems, we do not have heating.”

Mariupol’s mayor Vadym Boichenko accused the Russian military of creating a “humanitarian catastrophe” in the city in a post on his Telegram account Thursday.

“These scum have found no other way to break us. They are blocking the supply and repair of electricity, water and heat. They have also damaged the railways. They have destroyed bridges and smashed trains so that we can’t evacuate women, children and the elderly out of Mariupol,” he said.

“They are blocking food supplies, blocking us like in former Leningrad [during World War II], deliberately destroying the city’s critical life-support infrastructure for seven days. Again, we have no light, water or heat.”

He said the city was “working with international institutions to create a ‘green corridor’ for the humanitarian mission” and seeking to get a ceasefire so electricity supplies can be restored.

Deputy mayor: ‘We cannot collect all the bodies’

The Russian military announced advances in the Mariupol area Thursday morning.

“The units of the armed forces of the Donetsk People’s Republic narrowed the encirclement of the city of Mariupol, and also took control of the settlements of Vinogradnoye, Sartaka and Vodyanoye,” Maj. Gen. Igor Konashenkov, the Russian Ministry of Defense spokesman, said in a video briefing. He repeated claims the military was not targeting civilian areas in Ukraine.

A day earlier, Konashenkov outlined an evacuation corridor from Mariupol. “All civilians wishing to leave Mariupol, for security purposes, can go east along the Mariupol-Shirokino [Shyrokyne] road,” he said.

Russia routinely denies causing civilian casualties in Ukraine. However, CNN and other media and observers have extensively documented civilian casualties and damage to civilian infrastructure.

Orlov said that Russian shelling had targeted multiple civilian buildings, including homes, kindergartens and schools, but he cautioned that the civilian death toll in the city remains unclear.

“We do not know how many, because we cannot collect all the bodies and we cannot count,” Orlov said.

The situation in Mariupol “remains difficult,” a spokesperson for the Ukrainian National Guard told CNN, while stressing that the battle was not over.

“Soldiers of the National Guard of Ukraine, together with the Armed Forces, continue to defend the city,” the spokesperson said. “The Ukrainian military is not going to surrender the city and will strike at the occupying forces. The military will also continue to destroy enemy sabotage groups on the outskirts of Mariupol.”

Mariupol lies just to the west of the Donbas area of eastern Ukraine that has been controlled by Russian-backed separatists since 2014. Putin recognized the breakaway statelets of the Donetsk and Luhansk People’s Republics in the Donbas last month.

“It is quite clear that Putin is pushing for a land corridor to Crimea. I mean that is an obvious objective,” NATO’s former Deputy Supreme Allied Commander for Europe Richard Shirreff told CNN. Russia illegally annexed Ukraine’s Crimean peninsula in 2014.

Shirreff said he feared the latest push could cause a humanitarian catastrophe as civilian deaths rise and cities become ruins.

Kherson: Food, medicines in short supply, looting reported

The situation in Kherson, about 260 miles to the west of Mariupol, also appeared to be worsening Thursday.

One resident told CNN there had been chaos and panic in Kherson as people tried to get basic necessities. According to the resident, the city is suffering a severe lack of food and medicine – particularly insulin – with pharmacies being looted.

The resident added that there had been a significant amount of looting by Russian troops, and said that Russian soldiers had been seen arresting men.

Kherson’s mayor, Ihor Kolykhaiev, called on civilians to stop looting and stealing food supplies Thursday.

Kolykhaiev said in a Facebook post the “city needs food and industrial products” and called on residents to let the city handle distribution of products. “We guarantee that it will reach where it is now most expected – hospitals, orphanages, pensioners, needy, families with many children, social categories, etc,” he said.

On Wedneday, the mayor said on his Facebook page that the Ukrainian military was no longer in the city and that its inhabitants must now carry out the instructions of “armed people who came to the city’s administration” – indicating that the city has now fallen under Russian control.

Kherson resident Yaroslav Kontsevyi told CNN that Russian occupants have placed checkpoints and sniper points in key places of the city.

Kontsevyi said the Russian occupants were stopping civilian Ukrainian men and asking them if they were going to fight on the Russian or Ukrainian side in case of mobilization.

Another local resident also noted that there had been a significant amount of looting by Russian troops, and said that Russian soldiers had been seen arresting men.

A British military intelligence update released early Thursday noted that “some Russian forces have entered the city of Kherson,” but cautioned that the military situation on the ground “remains unclear.”

Hennadii Lahuta, head of the Kherson Regional State Administration, said in a statement that Russian forces had “completely occupied” the regional state administration building.

“We have not given up our responsibilities. The regional operational headquarters, which I lead, continues its work and addresses issues to help residents of the region. We are waiting for humanitarian aid,” Lahuta said.

A senior US defense official said the United States could not independently verify that the city of Kherson has fallen under Russian control.

Mariupol is still under Ukrainian control, according to the US defense official, but Russian forces are advancing on the city from the north and from the coastline with the apparent intention of isolating it.

The official added that there had been no “appreciable” moves by Russia, naval or otherwise, on the city of Odessa, further to the west.
