The French and German leaders have warned of "appropriate consequences" if the Ukrainian presidential election - scheduled for May 25th - does not go ahead as planned.
The two leaders issued a joint statement strongly hinting at further sanctions against Russia over its conduct towards Ukraine.
"If there is not an internationally recognized presidential election, that would lead unavoidably to a further destabilization of the country," it reads.
"Germany and France are in agreement that if that is the case then corresponding consequences would be drawn."
European Union foreign ministers added 13 people to their visa ban and asset freeze list over Ukraine's crisis.
Well that’s the voting over, and no surprises so far. A ‘Yes’ vote claimed to be 89% in Donetsk, and suddenly Ukraine is no more.
Nearly 90 percent of voters in eastern Ukrainian region voted for self-rule, the head of the separatist election commission said.
