Migrants aided by Belarus try to storm border into Poland

Hundreds if not thousands of migrants sought to storm the border from Belarus into Poland on Monday, cutting razor wire fences and using branches to try and climb over them. The siege escalated a crisis along the European Union's eastern border that has been simmering for months.

Poland's interior ministry said it had rebuffed the illegal invasion and claimed the situation was under control. The Defence Ministry posted a video showing an armed Polish officer using a chemical spray through a fence at men who were trying to cut the razor wire. Some migrants threw objects at police. Video footage from Belarusian media showed people using long wooden poles or branches to try to get past a border fence as police helicopters circled overhead.

Defence Ministry video taken later Monday showed the migrants settling in for the night by the border, having put up scores of tents and cooking meals.

"A coordinated attempt to massively enter the territory of the Republic of Poland by migrants used by Belarus for the hybrid attacks against Poland has just begun," a spokesman for Poland's security forces, Stanislaw Zaryn, said in a statement.

Noting that it's also NATO's eastern border, Zaryn stressed that the "large groups of migrants ... are fully controlled by the Belarusian security services and army." He accused Belarusian President Alexander Lukashenko of acting to destabilize Poland and other EU countries to pressure the bloc into dropping its sanctions on Minsk. Those sanctions were put into place after Belarus cracked down brutally on democracy protests.
