At least 21 killed, 112 wounded in shelling of Kharkiv: Ukrainian official

Highlights:

• Russia's defence ministry said on Wednesday Russian armed forces have captured the southern Ukrainian city of Kherson, RIA news agency reported
• US President Joe Biden warned Vladimir Putin that the Russian leader "has no idea what's coming", as Western nations tightened an economic noose around Russia, whose invading forces bombarded Ukrainian cities and appeared poised for an advance on Kyiv
• Russia's defence ministry urged Kyiv residents to flee and said it would strike unspecified areas used by Ukraine's security services and communications. Russia describes its assault on Ukraine as a special operation, not an invasion seeking territory
• A US official said a miles-long armoured column bearing down on the capital Kyiv had not made any advances in the past 24 hours, frozen in place by logistics problems, short on fuel and food, and perhaps pausing to reassess tactics
• Hundreds of thousands of Ukrainians have fled the fighting. West of Kyiv, in the city of Zhytomyr, four people, including a child, were killed on Tuesday by a Russian cruise missile, a Ukrainian official said
• Rocket strikes on the centre of Kharkiv killed at least 10 people and wounded 35, Ukrainian Interior Ministry adviser Anton Herashchenko said. Similar strikes that killed and wounded dozens in the city the previous day involved cluster bombs, experts said
• Kyiv's mayor published a video showing the moment when a tall TV antennae in the city was engulfed in flames, apparently hit by a rocket
• France declared an "all-out economic and financial war" against Russia, saying it would collapse the Russian economy as punishment for the invasion of Ukraine
• Ukrainian President Volodymyr Zelenskiy told Reuters Russia must stop bombing Ukrainian cities before meaningful talks on a ceasefire could start, as a first round of negotiations this week had yielded scant progress
• Russia's ambassador to the United Nations in Geneva, Gennady Gatilov, said his government sees "no desire on the part of Ukraine" to try to find a legitimate and balanced solution to the problems between the two countries

At least 21 people were killed and 112 wounded in shelling in the eastern Ukrainian city of Kharkiv in the last 24 hours, regional governor Oleg Synegubov said on Wednesday.

The authorities have said Russian missile attacks hit the centre of Ukraine's second-largest city, including residential areas and the regional administration building.
