Windows were smashed overnight on Sunday at the center that includes a mosque, a meeting center for Muslims, a shop and a restaurant. Security footage is being reviewed to identify those behind the assault, in which luckily no one was injured, Warsaw police spokesman Mariusz Mrozek said. Police have also appealed to the public to help catch the attackers, asking for witnesses to come forward.

"I am 100 percent sure this was a racist, anti-Muslim attack," leader of a Muslim community in Poland, imam Youssef Chadid told the media, as quoted by AP. There are two mosques in the capital of the largely Catholic country, including the one at the center that was attacked. Warsaw's Muslim community consists of some 22,000 people.
