Hundreds of people marched through Berkeley for a third night a row, blocking a major highway and stopping a train as activists in this ultra-liberal bastion protested grand jury decisions not to indict white police officers in the deaths of two unarmed black men on the other side of the country.

Protesters on Monday night blocked traffic on both sides of Interstate 80 in Berkeley, while another group stood and sat on train tracks, temporarily forcing an Amtrak train to stop.

The California Highway Patrol said a large group of demonstrators destroyed highway perimeter fencing, flooded lanes, and threw rocks and other objects at officers. There were 159 arrests in total. - AP
