MOSCOW, June 6 (Reuters) - The Kremlin said on Thursday that Western nations which supply Ukraine with weapons to directly strike Russian territory will definitely face consequences after President Vladimir Putin said he was considering arming the West's enemies in retaliation. Speaking with senior editors of international news agencies in St Petersburg on Wednesday, the Russian leader said Moscow was thinking about supplying advanced long-range weapons - of a similar nature to those the West is giving Ukraine - to the West's adversaries around the world.
