Western leaders warn Russia over Ukraine as Putin tests missiles

The shock of any invasion of Ukraine by Russia would "echo around the world", Boris Johnson has told world leaders.

He said we must be "unflinchingly honest" about the situation in Ukraine and should not "underestimate the gravity of this moment".

Western nations have warned Russia could invade Ukraine imminently, with over 130,000 of its troops near the border.

Russian President Vladimir Putin oversaw major drills of Russia's strategic nuclear missile forces from Moscow on Saturday.
