Russia's ambassador to the UK has blamed Britain for Ukraine's devastating drone attacks on its airfields.

As many as 40 Russian aircraft at five separate bases were destroyed by Ukraine as part of the covert Operation Spiderweb launched on Sunday.

But on Thursday night, the Kremlin turned its sights on Britain as its ambassador Andrea Kelin warned this country risks 'War World Three'.

Without offering any evidence Mr Kelin accused the UK military of being involved in Ukraine's attacks on targets inside Russia, highlighting its advanced geo-spacial data technology.

He issued his threat as President Trump told White House reporters he did not believe Russia and Ukraine would sign a peace deal.
