Latest news on Russia and the war in Ukraine

Humanitarian corridors will be opened in the Ukrainian cities of Mariupol, Melitopol and Energodar today, Ukraine’s Deputy Prime Minister Iryna Vereshchuk confirmed.

She said in a Telegram post that Russia had given “confirmation of its readiness” to comply with the corridors, which would allow the evacuation of civilians and the import of vital supplies.

Early attempts to evacuate civilians from Mariupol had to be halted when Ukrainian authorities said Russian troops were not honoring the cease-fire agreements that had been put in place.

Thousands of civilians are trapped in the city’s conflict zone, and are facing shortages of vital supplies including food, water and medicine.

Capturing Mariupol would be a key win for Russia, as it could allow Moscow to create a land corridor to Crimea, a peninsula in Ukraine’s south that it invaded and annexed in 2014.

Russian President Vladimir Putin has misjudged the situation in Ukraine, but his advisors are scared of telling him the truth about what’s happening on the ground, the head of Britain’s intelligence agency has said.

“It increasingly looks like Putin has massively misjudged the situation. It’s clear he misjudged the resistance of the Ukrainian people,” Jeremy Fleming, director of U.K. intelligence agency GCHQ, said in a speech in Australia on Thursday.

Referring to the conflict in Ukraine as Putin’s “personal war,” Fleming said the Russian leader had also underestimated the economic consequences of the sanctions regime as well as Russia’s military capabilities.

“We’ve seen Russian soldiers — short of weapons and morale — refusing to carry out orders, sabotaging their own equipment and even accidentally shooting down their own aircraft,” he said.

“And even though we believe Putin’s advisers are afraid to tell him the truth, what’s going on and the extent of these misjudgments must be crystal clear to the regime.”

David Arakhamia, a Ukrainian official who has taken part in negotiations with Russia, said in a video message that Russia and Ukraine would resume their talks on April 1.

Speaking on Ukrainian television, Arakhamia said the Russian negotiation team does not have any leeway and must discuss minor details of the talks with the Kremlin. But he said while Ukraine’s team had been given red lines by President Zelenskyy that were not to be crossed — such as conceding territory — they had room for much more flexibility than their Russian counterparts.

“Significant” Russian shelling and missile strikes have continued on the Ukrainian city of Chernihiv, and Russian troops are still holding positions close to Kyiv, despite promises to the contrary from Moscow, the United Kingdom said Thursday.

“Russian forces continue to hold positions to the east and west of Kyiv despite the withdrawal of a limited number of units,” the U.K. Ministry of Defence said in an intelligence briefing.

Chernihiv is about 90 miles (145 km) north of Kyiv and 40 miles (64 km) south of the Russian border.

A Russian defense official said Wednesday that Moscow would “drastically” reduce military activity near Chernihiv and the capital of Kyiv, NBC News reported.

U.S. Secretary of State Anthony Blinken urged caution about believing Moscow’s promises. The Russian Defense Ministry’s press office was not immediately available to provide comment to CNBC.

The British ministry said heavy fighting “will likely take place in the suburbs” of Kyiv in the coming days. Since last week, Ukrainian forces began to report retaking towns close to the capital.

The situation around the capital is fluid, and those Ukrainian claims are difficult or impossible to verify.

“You do see the Ukrainians trying to take advantage of opportunities and roll back the Russians where they can,” NBC News Global Security Reporter Dan De Luce said.

Heavy fighting continues in Mariupol in the south, but the U.K. Ministry said Ukrainian defenders are still holding the city center. Mariupol has been largely destroyed by Russian artillery and missiles.
