DONETSK, Ukraine (AP) -- Russian President Vladimir Putin said Thursday that Ukraine should withdraw its military units from the eastern and southern regions of the country, where anti-government insurgents are seizing buildings, but hours later, Ukraine's acting president ordered the military draft be renewed as the unrest intensifies.
Although Ukraine last year announced plans to end military conscription and transfer to an all-volunteer force, Oleksandr Turchynov said in his order that the draft must be renewed in light of threats of encroachment on Ukraine's territorial integrity and interference by Russia in the internal affairs of Ukraine.
Moscow has consistently denounced Ukrainian security forces' largely ineffectual anti-terrorist operation against the eastern insurgents and warned they shouldn't commit violence against civilians. In a telephone conversation with German Chancellor Angela Merkel, Putin said the removal of military units from the south and east was the main thing, but it was unclear if that could be construed as an outright demand.
Turchynov's order didn't specify where conscript-bolstered forces could be deployed. Earlier in the week, he said police and security forces had been effectively helpless against insurgents in the Donetsk and Luhansk regions, the heart of the unrest, and that efforts should be focused on preventing its spread to other parts of the country.
In the regional capital city of Donetsk, anti-government demonstrators took over the regional prosecutor's office Thursday. Several dozen riot police standing guard at the regional prosecutor's office fired stun grenades and tear gas when some at the front of the crowd of several hundred people attempted to force their way into the building in Donetsk.
As the confrontation escalated, some in the crowd threw rocks and managed to wrest away shields from police. An Associated Press reporter saw a handful of officers being dragged away and beaten by members of the crowd.
Hundreds of onlookers accompanying the protesters, who included several crying children, shouted slogans and hurled abuse.
A car outside the building blared out patriotic World War II music. Inside, a passenger waved a flag bearing a doctored image of Soviet leader Josef Stalin in a black vest and holding a machine gun superimposed with the words: Death to Fascism.
Upon occupying the building, protesters discarded the Ukrainian flag and replaced it with that of the Donetsk People's Republic - a movement that seeks either greater autonomy from the central government, or independence and possible annexation by Russia.
Donetsk is the heartland of support for Russia-friendly former President Viktor Yanukovych, who was ousted in February after months of protests in the capital. Opponents of the government that succeeded him have seized buildings in about a dozen cities and towns in eastern Ukraine.
Local news website Novosti Donbassa reported that earlier in the day around 30 armed men arrived in six cars in the town of Amvrosiivka, which lies close to the Russian border, and took over the city council and forced the mayor to resign.
On Wednesday, insurgents took control of the customs service building in Donetsk and city hall in Alchevsk, an industrial center of about 110,000 people, adding to the scores of buildings taken by the separatists over the past month in the east, where a dozen cities are now in the hands of the separatists.
There has also been a spate of reported kidnappings of pro-government politicians. The Svodoba nationalist party said a local party branch leader in Kostiantynivka, 65 kilometers (40 miles) north of Donetsk, initially managed to fight off attackers at his home, but was taken away as he was phoning for help.
Turchynov has twice proclaimed anti-terrorist operations to regain control of the east, but to little effect.
Unlike many recent seizures of the government offices, the assault on the prosecutor's office appeared to have been spearheaded by people armed with little more than sticks. At least one young man was seen by an Associated Press reporter with a handgun tucked into his trousers, however. At least one firebomb was thrown at the building during the clash.
The armed element of the insurgency is focused on Slovyansk, a city 110 kilometers (70 miles) north of Donetsk in which seven European observers from the Organization for Security and Cooperation in Europe remain held by pro-Russia gunmen.
Merkel on Thursday again called Putin and asked for his assistance in freeing the group. A spokeswoman for Merkel said the focus of the phone conversation between the two leaders was on the the continuing hostage-taking of the OSCE observers by separatists in eastern Ukraine. Spokeswoman Christiane Wirtz said in a statement that Merkel appealed to the president to use his influence in resolving the situation.
Russia denies allegations from Kiev and the West that it is influencing or fomenting the unrest in eastern Ukraine. The Kremlin also confirmed the conversation and said Putin stressed the main thing was for Ukraine to withdraw its troops from southeastern Ukraine, stop the violence and quickly start a broad national dialogue on constitutional reform.
On Wednesday, Ukraine's Foreign Ministry said it had detained the military attache at Russia's embassy on suspicion of spying and would remove him from the country. Russia has made no public comment on the issue.
