MINNEAPOLIS (AP) — Thousands of people marched in Minneapolis Saturday to protest the fatal shooting of a woman by a federal immigration officer there and the shooting of two protesters in Portland, Oregon, as Minnesota leaders urged demonstrators to remain peaceful.

The Minneapolis gathering was one of hundreds of protests planned in towns and cities across the country over the weekend. It came in a city on edge since the killing of Renee Good on Wednesday by an Immigration and Customs Enforcement officer.

“We’re all living in fear right now,” said Meghan Moore, a mother of two from Minneapolis who joined the protest Saturday. “ICE is creating an environment where nobody feels safe and that’s unacceptable.”

On Friday night, a protest outside a Minneapolis hotel that attracted about 1,000 people turned violent as demonstrators threw ice, snow and rocks at officers, Minneapolis Police Chief Brian O’Hara said Saturday. One officer suffered minor injuries after being struck with a piece of ice, O’Hara said. Twenty-nine people were cited and released, he said.

Minneapolis Mayor Jacob Frey stressed that while most protests have been peaceful, those who cause damage to property or put others in danger will be arrested. He faulted “agitators that are trying to rile up large crowds.”
