Latest news on Russia and the war in Ukraine

Russian authorities are likely keeping open the option of another round of call-ups under its “partial mobilisation” program, according to Britain’s Ministry of Defense.

In an intelligence update on Twitter, the ministry cited media reports last week suggesting Russian border guards were preventing dual passport-holding Kyrgyz migrant workers from leaving Russia, telling the men that their names were on mobilization lists.

Separately, on Jan. 23, the ministry noted that Kremlin spokesperson Dmitry Peskov said that the decree on the partial mobilization, announced by Russian President Vladimir Putin last September, “continues to remain in force, claiming the decree remained necessary for supporting the work of the Armed Forces.”

“Observers had questioned why the measure had not been formally rescinded,” the British ministry stated, adding that “the Russian leadership highly likely continues to search for ways to meet the high number of personnel required to resource any future major offensive in Ukraine, while minimising domestic dissent.”

There has been mounting speculation that Putin could announce another mobilization wave, given the Russian defense ministry’s recent announcement that it plans to beef up its combat personnel to 1.5 million people, from a current reported level of around 1.1 million.

Ukraine’s President Volodymyr Zelenskyy pressed allies for faster weapons supplies as fighting in eastern Ukraine, particularly in the Donetsk region, continues to be intense.

“The situation is very tough. Bakhmut, Vuhledar and other areas in the Donetsk region are under constant Russian attacks. There are constant attempts to break through our defense,” Zelenskyy said in his nightly video address Sunday.

“We are doing everything to ensure that our pressure outweighs the occupiers’ assault capabilities. And it is very important to maintain the dynamics of defense support from our partners,” he said, adding that “the speed of supply has been and will be one of the key factors in this war.”

“Russia hopes to drag out the war, to exhaust our forces. So we have to make time our weapon. We must speed up the events, speed up the supply and opening of new necessary weaponry options for Ukraine,” he said.

Ukraine’s allies Germany and the U.S. agreed last week to send Kyiv dozens of tanks, with other allies in Europe pledging to send their own German-made tanks as well, and the U.K. sending British tanks to Ukraine. Ukraine’s ambassador to France, Vadym Omelchenko, said on Friday that 321 Western tanks are set to be delivered to Ukraine.

Germany’s Chancellor Olaf Scholz insisted at the weekend that fighter jets would not be provided to Ukraine, telling a German newspaper that there should not be a “bidding war” over weaponry and that Germany “will not allow a war between Russia and NATO.”

Scholz reiterated Germany’s objections to sending fighter jets to Ukraine, telling the Tagesspiegel newspaper Sunday that there is no question of doing so.

“The question of combat aircraft does not arise at all,” Scholz said, according to Politico’s translation of the original story.

“I can only advise against entering into a constant competition to outbid each other when it comes to weapons systems,” he added.

Germany last week agreed to send 14 Leopard 2 tanks to Ukraine after months of resisting pressure to do so. Berlin also said it would allow other allies to send their own German-made tanks to Kyiv. The U.S. also agreed to send a number of M1 Abrams tanks.

Ukraine expressed gratitude for the decision to send tanks but immediately said it needed more firepower to counter Russia’s invasion, asking for fighter jets from its allies. One defense ministry advisor told CNBC he was sure Kyiv would receive F-16 fighter jets from its allies and that there should be no delay over the decision, as there was over tanks.

Over the weekend, another Ukrainian official said negotiations over the possible sending of attack aircraft to Ukraine were “ongoing.”

“Our partners understand how the war develops. They understand that attack aircraft are absolutely necessary to cover the manpower and armoured vehicles that they give us,” advisor to the head of the Office of the President Mykhailo Podolyak told the Freedom TV channel Saturday.

“In the same way, in order to drastically reduce the key tool of the Russian army – artillery, we need missiles. That’s why negotiations are already underway, negotiations are accelerating,” Podolyak said in comments translated by NBC News.

Ukrainian tank crews arrived in the U.K. over the weekend to begin training on Challenger 2 tanks that Britain has provided to the country.

The U.K. said it would provide 14 tanks earlier in January, ahead of the U.S. and Germany announcing last week that they too would provide tanks.

Tank crews will be trained to both operate and maintain the tanks, which will be delivered to Ukraine by March.
