A team of humanitarian workers from the International Committee of the Red Cross has been released after being held during an attempt to reach the southern Ukrainian city of Mariupol, according to Ukraine Deputy Prime Minister Irina Vereshchuk.

A team of ICRC representatives seeking to evacuate people from the besieged city of Mariupol had been held in nearby Mangush, Vereshchuk said, but after negotiations, they were released and sent to Zaporizhia — roughly 200 kilometers away.

Vereshchuk said that despite the Kremlin’s promises, Russian forces had not allowed anyone to travel to Mariupol. Vereshchuk said seven humanitarian corridors were in place on Tuesday.

Russian President Vladimir Putin is not ready to back down even though his army is doing much worse than expected, according to Angela Stent, a nonresident senior fellow at the Brookings Institution.

“He’s not willing to give up obviously, he’s going to keep striking,” she told CNBC’s “Street Signs Asia.”

Stent said Russia is not serious about peace talks yet, and Putin will not give up on his goal of weakening Ukraine.

“If he can’t subjugate it, at least make it very difficult for what’s left of the government in Kyiv to function,” she said, adding that Putin also wants to take over the Donbas region fully. The Donbas is a breakaway region in eastern Ukraine which includes Donetsk and Luhansk, two pro-Russian self-proclaimed republics.

“He would like to do that in time for May the 9th, when the Russians will have their parade in Moscow commemorating victory in World War II,” said Stent, referring to what Russian call “Victory Day.”

Ukraine President Volodymyr Zelenskyy has warned that reported atrocities in Borodyanka, an urban settlement near Kyiv, could be worse than the devastation seen in Bucha.

Speaking in his nightly address to the Ukrainian people, Zelenskyy said more than 300 were killed and tortured in the town of Bucha, a suburb near the capital of Kyiv. However, the number of victims of Russia’s onslaught in Borodyanka could be even larger.

“We already have information that in Borodyanka and some other freed towns, the amount of victims can be even larger,” Zelenskyy said via Telegram, according to a translation.

“The occupiers will be held responsible. We are already doing everything as fast as we can to find all the Russian soldiers involved in these crimes,” he added.

China’s Foreign Minister Wang Yi spoke to his Ukrainian counterpart, Dmytro Kuleba, on a phone call state media said was made at Ukraine’s request.  

This is the first reported high-level conversation between the countries since March 1, when Kuleba asked Beijing to use its ties with Moscow to stop Russia’s invasion, the Ukrainian foreign ministry said at the time.

Wang repeated China’s message that peace and stability should be achieved through negotiation, according to state media.

Kuleba tweeted: “Grateful to my Chinese counterpart for solidarity with civilian victims.”

“We both share the conviction that ending the war against Ukraine serves common interests of peace, global food security, and international trade,” he added.
