Ukraine tensions: Russia begins military drills with Belarus

Russia and Belarus have started 10 days of joint military drills amid ongoing fears of a Russian invasion of Ukraine.

Belarus is a close ally of Russia and has a long border with Ukraine.

France called the drills - believed to be Russia's biggest deployment to Belarus since the Cold War - a "violent gesture". Ukraine says they amount to "psychological pressure".

UK Prime Minister Boris Johnson said on Thursday that Europe faces its biggest security crisis in decades.
