Before President Biden's first State of the Union address, we asked some Americans in Philadelphia how they feel about the US response to the war in Ukraine. The US and its North Atlantic Treaty Organization (Nato) allies have been sending weapons to Ukraine to help it fight against Russia. Mr Biden has said that the US will not send troops to fight in Ukraine. Western nations have also imposed economic sanctions designed to punish Russia for invading.

Ukraine President Volodymyr Zelensky has accused Russian President Vladimir Putin of war crimes, following an attack in the country's second largest city, Kharkiv. Russian missiles and rockets have hit the cultural heart of the city, where an opera house, concert hall and government offices were struck in Freedom Square. Russia has previously denied targeting residential areas, but the International Criminal Court - which examines war crimes - is looking to open an investigation.

Ukraine President Volodymyr Zelensky was greeted with a standing ovation as he addressed the European Parliament today. He said that he was ”happy that we have unified today, all of the members of the European Union,” but that it was a very high price to pay. In contrast, there was a mass walkout from the UN’s Human Rights Council when Russia’s foreign minister addressed the meeting. In his speech he accused the Ukrainian government of playing “dangerous games linked to plans to acquire their own nuclear weapons”.

The Ukrainian resistance has slowed the advance on Kyiv but there is a 40-mile-long convoy of Russian military vehicles approaching the Ukrainian capital and Russian bombing of the city has caused civilian casualties. President Zelensky has accused Russia of committing war crimes in targeting civilian targets in the city and around the country. For now, as Russian troops approach Kyiv citizens are preparing to fight.

UK Prime Minister Boris Johnson was confronted by a Ukrainian journalist at a press conference in Warsaw, Poland. The journalist, who said she was from Kyiv and had family and colleagues still in Ukraine, accused Nato of being unwilling to enforce a no-fly zone out of fear of a World War Three that has “already started”. "We are crying, we don't know where to run," she told him. The UK prime minister said that “direct combat” with Russia was not something the UK could do, but he was "doing everything we can to tighten the economic noose".
