BRUSSELS, March 6 - Leading Ukrainian politician Yulia Tymoshenko on Thursday called for Europe to take strong action over Crimea's attempt to join Russia, warning that otherwise Moscow would move to take over the rest of Ukraine and destabilize the continent, Reuters reported.

Speaking hours after the parliament of the Ukrainian region of Crimea voted to join Russia, a visibly emotional Tymoshenko warned that Russian President Vladimir Putin would take advantage of any weakness by the West.
