KIEV (Reuters) - Separatist protesters on Sunday seized control of the mayor's office in the town of Mariupol, eastern Ukraine, on the Azov Sea, local media said.

The protesters entered the building following a rally involving about 1,000 people demonstrating in favour of the creation of a separate republic in eastern Ukraine, a local journalist for the newspaper Priazovsky Worker said.

The police did not try to stop them. They entered the offices, took down the Ukrainian flag and were erecting barricades outside the building, the journalist said.

Ukrainian security forces launched an operation on Sunday to clear pro-Russian separatists from a police headquarters in the eastern city of Slaviansk, with Kiev reporting dead on both sides as it combats what it calls an act of aggression by Moscow.

Ukraine faces a rash of rebellions in the east which it says are inspired and directed by the Kremlin. But action to dislodge the armed militants risks tipping the stand-off into a new, dangerous phase as Moscow has warned it will protect the region's Russian-speakers if they come under attack.

One Ukrainian state security officer was killed and five wounded on the government side in what Interior Minister Arsen Avakov called Sunday's "anti-terrorist" operation.

"There were dead and wounded on both sides," Mr Avakov said on his Facebook page, adding that there had been an "unidentifiable number" of casualties among the separatists, who were being supported by about 1,000 people.

Kiev accuses Moscow of trying to deepen violence and chaos in Ukraine, a former Soviet republic it once ruled. The Kremlin, it says, wants to undermine the legitimacy of presidential elections on May 25 which aim to set the country back onto a normal path after months of turmoil.

Relations between Russia and the West are at their worst since the end of the Cold War, the result of the crisis that began when the Moscow-backed Ukrainian president was pushed out and Russia annexed Crimea from Ukraine.

Moscow justified sending its military into Crimea, on Ukraine's southern tip, by saying the Russian population there was under threat, and some in Western governments believe the Kremlin is preparing a similar scenario for eastern Ukraine.

A Reuters reporter in Slaviansk, about 150 km from the Ukraine-Russia border, said two military helicopters were flying over the town's police headquarters where the militants were holed up.

Earlier, Mr Avakov had warned residents to stay indoors. "Pass this on to all civilians: they should leave the centre of town, not come out of their apartments, and not go near the windows," he wrote on his Facebook page.

In the nearby town of Kramatorsk, militants exchanged gunfire with the police late on Saturday, though there was no confirmation anyone had been hurt.

In Washington, the White House expressed concern that the seizures of public buildings in eastern Ukraine could be a prelude to a Russian military incursion, though Moscow has strenuously denied any such intention.

"We call on President (Vladimir) Putin and his government to cease all efforts to destabilize Ukraine, and we caution against further military intervention," said Ms Laura Lucas Magnuson, spokesman for the White House National Security Council.

US Vice-President Joe Biden will travel to Kiev on April 22, becoming the most senior US official to visit the country since the crisis began there.

Russian Foreign Minister Sergei Lavrov said it was Ukraine's Western-leaning government, viewed by the Kremlin as illegitimate, that was stoking the tensions.

Any use of force against Russian speakers "would undermine the potential for cooperation" between Moscow and Western powers over Ukraine, Lavrov said in a statement after a telephone call with his US opposite number John Kerry.

United Nations Secretary-General Ban Ki Moon said in a statement he was deeply concerned about the deteriorating situation in eastern Ukraine and "the growing potential for violent clashes".

The crisis over Ukraine could trigger a "gas war", disrupting supplies of Russian natural gas to customers across Europe. Moscow has said it may be forced to sever deliveries to Ukraine - the transit route for much of Europe's gas - unless Kiev settles its debts.

For now though the focus of the crisis was in eastern Ukraine, the country's industrial heartland where many people feel a close affinity with neighbouring Russia.

Nato says Russian armed forces are massing on Ukraine's eastern border, while Moscow says they are on normal manoeuvres.

On Saturday, in what had the look of a coordinated action, pro-Russian militants, some of them armed, seized public buildings in several towns, challenging Kiev's already shaky control over the region.

In Kramatorsk, about 15km south of Slaviansk, gunmen seized the police headquarters after a shootout with police, a Reuters witness said.

The attackers were a well-organised unit of over 20 men, wearing matching military fatigues and carrying automatic weapons, who had arrived by bus. Video footage showed the men taking orders from a commander. Their identity was unclear.

Their level of discipline and equipment was in contrast to the groups who have occupied buildings so far in Ukraine. They have been mostly civilians formed into informal militias with mismatched uniforms.

Ukrainian police appeared powerless to intervene, and it was not clear if local security forces were still taking orders from Kiev. The police chief for the Donetsk region, which includes Slaviansk, resigned after pro-Russian protesters picketed his headquarters.

In Slaviansk, militants blocking the road leading into the city from the north set fire to tyres and trees, hoping the smoke would hamper any operation by government forces.

By the side of one road leading into the city, a group of women were praying with a priest. Not far away, a group of about 12 armed men in combat fatigues, helmets and balaclavas and carrying automatic weapons appeared to be monitoring people on the road.

"We want to join Russia. We would be very grateful if Russia helps us," said a gunman in the centre of Slaviansk who gave his name as Alexander, wearing camouflage fatigues and a black balaclava mask. "We will stand until victory. Honestly, it's not scary for me to die for freedom."

Ukrainian commentator Sergei Leshchenko said the burst of activity by pro-Russian groups was an attempt by the Kremlin to secure a strong negotiating position before international talks about Ukraine. Representatives of Russia, Ukraine, the United States and the European Union are due to meet in Geneva on Thursday for the talks.

Russia is expected to argue for a revamp of Ukraine's Constitution to give a large degree of autonomy to eastern Ukraine, something Kiev and its Western backers reject.

"Russia will come to the talks with the position that 'Donetsk and several neighbouring regions are already ours - now let's talk about federalisation'," said Mr Leshchenko, a commentator with the Ukrainska Pravda newspaper.
