SOKOLKA: Polish forces fired tear gas and deployed water cannons against stone-throwing migrants trying to cross the border from Belarus on Tuesday, as Belarusian leader Alexander Lukashenko claimed he wanted to avoid a "confrontation", reports AFP.
Polish border guards estimate up to 4,000 migrants are currently camped out along the border between Poland and Belarus in increasingly dire conditions and freezing temperatures.
A standoff near the Bruzgi-Kuznica border crossing on the EU's eastern frontier began last week when hundreds of migrants gathered there.
"Migrants attacked our soldiers and officers with rocks and are trying to destroy the fence and cross into Poland," Poland's defence ministry said on Tuesday, tweeting a video showing apparent clashes at the border. "Our forces used tear gas to quell the migrants' aggression."
Polish police said an officer was seriously injured with a likely skull fracture in the clashes, and said stun grenades and tear gas canisters had also been thrown at officers.
Russia condemned Poland's use of tear gas and water cannons against the migrants, with Foreign Minister Sergei Lavrov calling it "absolutely unacceptable". Lukashenko told a government meeting on Tuesday: "We cannot let this so-called problem lead to heated confrontation."
"The main thing now is to protect our country and our people, and not to allow clashes," he added, according to state news agency Belta.
Merkel's office said the pair discussed bringing humanitarian aid to the migrants, whose number includes many young children.
Lukashenko -- in power since 1994 and accused by the West of rigging an election last year -- said he and Merkel agreed the standoff should be defused.
"We were of the united opinion that nobody needs escalation -- not the EU, or Belarus," he said.
But he said he had "differing" views with Merkel on how the migrants got to Belarus, with the West saying Minsk had brought them there as revenge for sanctions.
EU foreign ministers on Monday agreed that existing sanctions targeting Lukashenko's regime will be expanded to include individuals or companies found to have encouraged border crossings.
The US has also vowed to expand its sanctions on Belarus.
Iraq has said it will start voluntary repatriations of its citizens from Belarus this week.
The Iraqi embassy in Moscow said it would fly out around 200 people in a flight on Thursday.
But many migrants -- including those AFP spoke to -- have vowed not to go back.
The EU meanwhile has been asking for the flights to Belarus to stop.
Turkish Airlines has now banned Iraqis, Syrians and Yemenis from flying to Belarus via Turkey and private Syrian carrier Cham Wings Airlines has said it will halt flights to Minsk.
Belarus's state-run airline Belavia has also said that Syrians, Iraqis, Yemenis and Afghans are banned from incoming flights from the United Arab Emirates at Dubai's request.
At least 11 migrants have died on both sides since the influx started in the summer, according to aid groups.
One of them, a 19-year-old Syrian man from the war-torn city of Homs, was laid to rest on Monday in a cemetery near the border belonging to Poland's tiny ethnic Muslim community.
