Russia has summoned the Finnish ambassador in Moscow, after Finland signed a new agreement on military co-operation with the US.

Monday’s deal grants the US broad access to the area of Finland’s long border with Russia.

Moscow said it would “take necessary measures to counter the aggressive decisions of Finland and its Nato allies”.

Finland joined Nato this year in response to Russia’s Ukraine invasion.

Russian President Vladimir Putin recently accused Nato of having “dragged” Finland into the bloc, and announced the creation of a new military district near Finland’s border.
