Police order protesters to disperse outside Portland building

Police officers were hit by rocks and bottles during a protest in the Oregon city of Portland late on Saturday and police told people to leave the area or face arrest. In a Twitter post, the police said they had declared a riot for the gathering around the Penumbra Kelly Building, a city building that houses offices including police.

"Failure to leave may subject you to arrest, citation, or crowd control agents, including but not limited to tear gas and/or impact weapons," the statement added.
