Minnesota police pelted with rocks, rebar; 102 arrested after protests turn violent

More than 100 people were arrested and 21 police officers injured in Minnesota Saturday night when protests over recent police killings of black men morphed into rioting.

St. Paul Mayor Chris Coleman detailed at a Sunday press conference what he called an "extreme incident" Saturday night that led to 102 arrests after protesters pelted police officers with rocks, rebar and incendiary devices, including Molotov cocktails. The injuries to officers were "significant, but none were life-threatening," Coleman said.

The protests, which started with a march from the governor's mansion around 8 p.m., were among several demonstrations nationwide following the deaths of 32-year-old Philando Castile, a black man who was shot in a Minneapolis suburb by a police officer during a traffic stop, and 37-year-old Alton Sterling in Baton Rouge, La. Sterling, who was black, was shot after a scuffle with officers outside a convenience store.

The riots came just days after five Dallas police officers were murdered by Micah Johnson, who targeted white cops in a sniper attack last Thursday. Sterling's and Castile's families denounced the attack on the Dallas officers.
