A Ukrainian missile strike has hit the headquarters of Russia’s Black Sea fleet in Crimea.
One soldier is missing after the missile attack, according to Moscow. Footage on social media shows plumes of smoke over the building in Sevastopol.
The fleet is an important target for Kyiv and is seen as the best of Russia’s navy.
Ukraine has hit several targets in Crimea recently, including an air-defence system and two naval vessels.
Against the backdrop of the attack, Ukrainian President Volodymyr Zelensky visited the Canadian parliament to give a speech in which he thanked Canada for being an “example for others around the world” in its support of his country.
Canada is home to a large Ukrainian diaspora.
Mr Zelensky, who was given multiple standing ovations, said “people will be the winners, not the Kremlin” and insisted Ukraine could call on support as it was about “saving lives of millions of people”.
Canadian Prime Minister Justin Trudeau pledged additional support worth 650m Canadian dollars ($482m, £394m), including 50 armoured vehicles and training for F-16 fighter jet pilots and engineers.
