Russia this morning threatened to strike US air bases in Poland with 'advanced weapons' hours after it reportedly launched an advanced missile as part of a brutal barrage of targets across Ukraine.

Moscow said the opening of a new US ballistic missile defence base in Redzikowo near the Baltic coast will 'increase the overall level of nuclear danger', adding it had been added to a list of possible targets for Russia.

The facility, opened on November 13, forms part of a broader NATO missile shield called 'Aegis Ashore' designed to intercept short- and intermediate-range ballistic weapons.
