At least 31 people died in Odessa, Ukraine this evening after a building was set on fire during clashes between Ukrainian government supporters and pro-Russian protesters.

The fire broke out in the House of Trade Unions building, which has served as make-shift headquarters for pro-Russian separatists in the city. Eight people reportedly died after jumping from the burning building; the others reportedly died from smoke inhalation.

A local parliamentarian told Reuters that six pro-Ukraine protesters also died in the protests.
