Ukraine’s parliament voted on Tuesday to give the International Criminal Court the authority to try ousted President Viktor Yanukovich for his alleged role in the deaths of over 100 protesters.

The vote comes a day after the interim government issued an arrest warrant for Yanukovich, who has been missing since last week.

Acting President Olexander Turchynov, meanwhile, has issued warnings of a “serious threat” of separatism, and pushed back until Thursday a vote on selecting a new unity government.
