Myanmar police have arrested two Buddhist extremists and are seeking to arrest more after the hardline Buddhist nationalists clashed with Muslims in Yangon city.

The arrests came after the extremists, led by the Patriotic Monks Union (PMU), attacked flats on Tuesday in a Yangon district with the Muslim population.

The incident has ignited clashes that were broken up by the police.

Myanmar police have been increasingly concerned over the rising of religious tensions in the region.

Also two weeks ago, the extremists forced the closure of two Muslim schools.

In both incidents, PMU monks as well as lay sympathizers targeted Muslim areas after attending a trial of fellow nationalists facing charges for inciting violence.

“We have arrested two people since yesterday evening, and are still looking for the rest of them,” according to Police Major Khin Maung Oo, who is in charge of the police station in Yangon's Mingalar Taung Nyunt district, where the clashes broke out.

Leaders of the PMU noted that they were acting independently of the Ma Ba Tha, a very influential hardline Buddhist organization that propagates anti-Muslim feelings among Buddhist nationalists.

Ma Ba Tha’s firebrand monk Wirathu, who has become infamous for his Islamophobic sermons, once called himself “Myanmar's Bin Laden”.
