Hello and welcome to the Guardian’s live coverage of Russia’s war on Ukraine.

The UK’s prime minister, Keir Starmer, has arrived in Kyiv to sign a security and trade pact with Ukraine, in a public show of support for Volodymyr Zelenskyy before the much anticipated return of Donald Trump to the White House on Monday.

The two countries will sign a partnership deal to deepen the existing defence relationship, with further military assistance to Kyiv on offer amid concerns Trump could reduce aid to Kyiv at a time when Russia continues to make battlefield gains.

Starmer, who is today making his first visit to Ukraine since he became prime minister last July, was due to sign a 100-year partnership with Kyiv, which will be laid before the British parliament in the coming weeks.

Starmer’s office said the treaty, aimed at deterring ongoing Russian aggression, will bolster military collaboration by seeking to strengthen security in the Baltic Sea, Black Sea and Azov Sea.

Zelenskyy had earlier said that he and Starmer would discuss the possibility of having western troops stationed in Ukraine to oversee a ceasefire agreement, a divisive proposal initially put forward by French President Emmanuel Macron.

Trump has vowed to end the war within 24 hours of taking office, without specifying exactly how. It is expected that pressure for negotiations will mount when his administration takes over next week.

Trump’s nominee for secretary of state, Marco Rubio, told the Senate foreign relations committee that the new administration would seek “bold diplomacy” to end the war. “There will have to be concessions made by the Russian Federation, but also by the Ukrainians,” he said yesterday.

Here are some of the other latest developments:

• The Ukrainian military said on Thursday that its forces had captured more than two dozen troops in the western Russian region of Kursk, where Russian troops have been trying to eject Ukrainian forces for the past five months. “Ukrainian paratroopers together with adjacent units captured 27 enemy servicemen in the Kursk region,” a military statement said, adding that the Russian troops had surrendered.

• Ukraine downed 34 out of 55 drones launched by Russia across 11 of the country’s regions in an overnight attack, the Ukrainian air force said, with a further 18 failing to reach their targets.

• Russia launched missiles and drones at Ukrainian energy facilities on Wednesday, one day after Kyiv said it had carried out its largest aerial attack of the war on Russian army factories and energy hubs hundreds of kilometres from the frontline. The mayor of the southern city of Kherson said there were power cuts as a result of the barrage. After the attack, Zelenskyy called on the west to use around US$250bn of unallocated frozen Russian assets to buy Kyiv weapons.

• Europe must “take responsibility” for its own security, Poland has told its fellow EU member states, as Warsaw takes over the rotating presidency of the bloc at a time of increasing geopolitical uncertainty.
