Russia-Ukraine war at a glance: what we know on day 577 of the invasion

Ukraine’s military said its forces had “successfully” struck the headquarters of Russia’s Black Sea navy in the Crimean port of Sevastopol on Friday. Russia’s defence ministry said that one military serviceman was missing. Footage posted on social media showed clouds of white smoke billowing from the rooftop of the HQ building. Russian sources reported that the strike was carried out using Storm Shadow missiles provided by the UK and launched from Ukrainian aircraft.

A Russian missile strike on civilian infrastructure in Kremenchuk in the central Poltava region of Ukraine killed one person and injured 15 others, the regions’ governor, Dmytro Lunin, said on Friday via Telegram. He said one child was among the injured and that Ukrainian air defences downed one of the missiles launched.

Volodymyr Zelenskiy has bolstered military aid to Ukraine following a visit to Canada, with Ottawa promising an extra C$650m ($482m) over the next three years. Canada’s prime minister, Justin Trudeau, said the aid included money for 50 armoured vehicles. He will also send F-16 trainers for pilots and maintenance so Ukraine is able to maximise its use of donated fighter jets.

Zelenskiy thanked Canada for its military support, and hailed the historic and communal ties between the two countries, in an impassioned speech at the Canadian parliament on Friday. “You’re always on the bright side of history … I have no doubt that you will choose the side of freedom and justice,” the Ukrainian president said.

The US president, Joe Biden, has told Volodymyr Zelenskiy that the US will provide a small number of long-range missiles to help in Ukraine’s fight against Russia, three US officials and a congressional official told NBC News on Friday. The officials did not confirm when the missiles would be delivered.

The Russian deputy prime minister, Alexander Novak, held a meeting with Russian oil company managers on Friday to discuss the domestic fuel market, the government said. Russia temporarily banned exports of petrolium and diesel to all countries outside a circle of four ex-Soviet states with immediate effect, the government said on Thursday, without a specified end date.
