Russia attacks key Ukraine cities as invasion intensifies

Russia intensifies its attacks on key Ukrainian cities - with fighting raging for a seventh day in the north, east and south.

Russian paratroopers have landed in Kharkiv in the north-east, Ukraine says, with heavy fighting reported, reports BBC.

In the south, Russia says it has taken control of the port of Kherson but its mayor says it's still held by Ukrainian forces.

A 40 mile-long convoy of Russian armoured vehicles is about 15 miles north of the capital Kyiv.

Meanwhile, the US says it will ban Russian airlines from its airspace - following the lead of the European Union and Canada.

Major companies such as Apple, Google, Ford and Exxon Mobil have taken steps against Russia over the invasion.

Stock market trading on the Moscow Exchange is suspended for a third day, says Russia's central bank.
