A deadline for pro-Russian militants to hand over their weapons and leave buildings they have occupied in eastern Ukraine has passed without signs of rebels complying.
As the 9am deadline issued by authorities in Kiev expired on Monday, Reuters news agency reported that there was no outward sign the rebels were complying with the ultimatum in the city of Slovyansk.
Eastern Ukraine is on edge as acting president Oleksandr Turchynov threatens to launch what he called a "full-scale anti-terrorist operation" against pro-Russians who have seized government buildings.
Turchynov has promised amnesty for those who give up their weapons and come out peacefully. But he says he will not let Russia take over eastern Ukraine the way it annexed Crimea last month.
So far, there are no signs the pro-Russian demonstrators are heeding the president\’s demands.
There was no immediate comment from the government on the deadline passing.
Armed men have raised a Russian flag at a police and security headquarters that they seized on Saturday morning, in the latest takeover of a public buildings by Pro-Russian protesters in eastern Ukraine.
Gunmen occupied a police station and a security services building in the town of Sloviansk. Official buildings in Druzhkovka were reportedly taken over.
At least 20 men armed with pistols and rifles took over the police and security services headquarters in the city, about 150km from the border with Russia.
Officials said the men had seized hundreds of pistols from arsenals in the buildings. The gunmen replaced the Ukrainian flag on one of the buildings with the red, white and blue Russian flag.
The conflict between pro-Russian gunmen and Ukraine’s authorities turned bloody on Sunday, with one security service officer killed and reports of people wounded on both sides, as the struggle for the country’s east escalated one week after separatists began systematically occupying government buildings.
The new administration in Kiev is struggling for credibility in the east of the country and several towns and cities were effectively taken over by pro-Russian groups over the weekend.
Sloviansk, in the Donetsk region, is completely surrounded by rebel barricades and checkpoints manned by pro-Russian militia are stationed on major roads leading into the city.
Although Kiev has promised to take back control of Sloviansk, an all-out assault carries huge risks and could trigger a reaction from Russia, which has tens of thousands of troops camped near its border with Ukraine.
