WARSAW, Poland (AP) — A top Polish human rights official is encouraging people to attend a concert Monday in support of a Chilean pianist who was recently beaten by skinheads who mistook him for an Arab.

The attack occurred amid a rise in Islamophobia in Poland even though the country has not yet taken in any of the Muslim migrants who began arriving in Europe last year in large numbers. Dozens of Syrian Christians were granted asylum in Poland last year, though most left quickly for Western Europe. Last year Poland pledged to take up to 7,000 migrants though only a fraction of those are expected this year.

Poland's Commissioner for Human Rights Adam Bodnar, is calling on people to attend a concert Monday evening in Warsaw to show solidarity with Christiano Ramos, the Chilean who was attacked recently on a train near Warsaw.

Ramos, who has lived in Poland for many years, lost a tooth and was injured in the head.

Bodnar said the idea is to convince Ramos and others like him that they "have many friends in Poland, that Polish society might be different, and that he should not decide to leave our country."

Bodnar says there has been an outpouring of hate speech against Arabs in recent months that has translated into violent incidents. Some newspapers have stopped allowing readers to post comments below stories on migration topics, he said.

"Unfortunately, massive hate speech towards Arabs translates into hate violence incidents," Bodnar said. "Basically every two weeks we can identify a situation when somebody is attacked, because he looks 'like an Arab.'"

Last year a Syrian Christian was attacked in the Western Polish city of Poznan. A court on Monday sentenced one of his attackers to two years in prison, and a second to three months.
