BERLIN (AP) — Hundreds of demonstrators protesting against gentrification clashed with police in the eastern German city of Leipzig for a third night in a row, injuring 11 officers, police said Sunday.

The protests, which started Thursday night, began after police ended the squatting of two buildings in the city last week, the German news agency dpa reported.

The report said that during the riots on Saturday night, police were attacked with fireworks and pelted with stones. Protesters build street barricades and and put garbage cans on fire.

The pilot of a police helicopter hovering over the protests in the Leipzig neighborhood of Connewitz was blinded by a laser, dpa said. Several protesters were temporarily detained to verify their identities.
