Ukrainian President Petro Poroshenko has warned that he may soon end a week-long ceasefire as pro-Russian separatists continue to attack his troops.
The Ukrainian presidential office said in a statement on Tuesday that Poroshenko has instructed government forces in eastern Ukraine to fire back if attacked.
Last Friday, Poroshenko declared the ceasefire as part of a peace plan to bring stability to the region. He halted the military operation on his side and called for pro-Russian soldiers to disarm within 7 days.
The leaders of the pro-Russian armed forces agreed to accept the ceasefire on Monday. But pro-Russian soldiers in Slovyansk later shot down a military helicopter, killing all 9 soldiers on board.
