Russian troops \\\'overrun Crimea base\\\'

Russian troops have seized control of a Crimean naval base at Feodosia, the third such attack in 48 hours, Ukrainian officials have said. Defence spokesman Vladislav Seleznyov said the Russians had attacked the base from two directions using armoured personnel carriers and stun grenades. Russia has taken over most of Ukraine's military bases in Crimea. The G7 group of industrialised countries is to consider a collective response to the crisis in The Hague. Leaders of the G7 will hold talks on Monday on the sidelines of a long-planned summit on global threats to nuclear security.
