In a demonstration that raged for hours and turned violent Thursday, hundreds of protesters blocked streets and the light rail in Jerusalem, and marched on the prime minister’s home, alleging that racism played a part in acts of police brutality directed at Israelis of Ethiopian descent, Times of Israel reported.

When the protesters, mostly from the Ethiopian community, tried to march on the Prime Minister’s Residence, they were kept at bay by police.

Three police officers were injured by rocks and bottles thrown by the protesters in the ensuing clashes, and as many as 13 demonstrators were wounded. Two were arrested.

Police used crowd control methods to block the protesters, including tear gas, stun grenades and fire hoses.
