The mayor of Hostomel has been shot and killed while out distributing aid, according to Ukrainian officials

The town is close to the Ukrainian capital Kyiv, and is home to the Hostomel airfield, a key strategic point at the centre of fighting between Russian and Ukrainian forces. The town council said Yuri Prylypko died while distributing bread and medicines to those in need. He was killed along with two others, Ruslan Karpenkom and Ivan Zore. A statement by the Hostomel council said he "died as a hero", adding it is impossible for a funeral to immediately be held due to the war. In other news: Boris Johnson has suggested that Vladimir Putin is "plainly doubling down" on his military tactics in Ukraine, as he warned that attacks on civilian areas across the country will likely continue. Speaking during a press conference at Downing Street on Monday, Mr Johnson described the Russian president's tactics as "repugnant" and vowed that additional sanctions against Moscow would be implemented. “The president of Russia is plainly doubling down," he said during the conference, which included the Canadian Prime Minister Justin Trudeau and Dutch Prime Minister Mark Rutte. “ He has decided that he is going to continue with an all-out onslaught on centres of habitation in a way that we think is utterly repugnant. “It’s clear that we’re going to have to do more.” Mr Johnson said that a core part of the strategy to isolate Russia was to decrease the reliance on Russian energy and to try to find alternative sources instead. "We are going to have to look for substitute supplies from elsewhere and we are going to have to do it together across the entire coalition of countries that is now condemning Putin’s actions,” Mr Johnson told the press conference * On the outskirts of Kyiv, in the suburb of Irpin, there has been continued Russian shelling, but authorities say 2,000 people have managed to leave via a makeshift bridge. Also near the capital, in Hostomel, the village council says Mayor Yuri Prylypko was shot dead while distributing bread and medicines. The strategic Hostomel airfield is nearby. Meanwhile in the south, the city of Mykolaiv has come under attack. Ukraine says artillery hit residential areas overnight in the city, which stands between Russian-annexed Crimea and the southern port city of Odesa. Tens of thousands of civilians remain trapped in the large port city of Mariupol without power and with food and water in short supply. A family that escaped told AFP news agency they had seen "bodies everywhere". Controlling Mariupol would give Russia a land corridor between Crimea and the Russian-backed regions of Luhansk and Donetsk.
