Day 21 of the war: How is the situation in Ukraine

· There are "fundamental contradictions" in the talks aimed at ending Russia's military offensive in Ukraine, but compromise is possible, said a member of the Ukrainian delegation and the president's aide, Mykhailo Podolyak. "We continue tomorrow. A very difficult and viscous negotiation process. "

The President of Ukraine, Volodymyr Zelensky, told reporters that "with such allies we will win this war" after the Prime Ministers of Poland, the Czech Republic and Slovenia made a dangerous train trip to Kiev to offer their support. They are the first Western visitors to Kiev since the start of the war two weeks ago.

Russian forces reportedly took patients and medical staff of a hospital in the city of Mariupol hostage. According to the BBC, the city's deputy mayor Sergei Orlov said there were 400 people in the hospital and the Russian army was "using our patients and doctors as hostages".

· A series of Russian attacks hit a residential neighborhood in the capital on Tuesday morning, causing a fire in a 15-storey apartment building. Zelensky said five people were killed in the airstrikes.

· Nearly 100 children have died in Ukraine, Zelensky said in a virtual speech to Canadian lawmakers. He urged Canada and its allies to do more to stop the Russian occupation, including establishing a no-fly zone because civilian casualties are increasing every day.

· The UK will impose sanctions on 370 other Russian individuals, including more than 50 oligarchs and their families with a combined net worth of approximately $ 130 billion. More than 1,000 individuals and entities have been targeted by sanctions since the invasion of Ukraine.

· Boris Johnson will visit Saudi Arabia and the United Arab Emirates on Wednesday to be asked to produce more oil and help the UK reduce its dependence on Russian oil. The move sparked protests, following reports that Saudi Arabia had executed 81 people just days earlier.
