Protesters shut down Interstate 94 near downtown St. Paul

(AP) — Police used smoke bombs to clear demonstrators blocking Interstate 94 in St. Paul late Saturday night during a protest sparked by the recent police killings of black men in Minnesota and Louisiana.

The smoke was used after about 200 protesters refused to leave the roadway just after midnight as police in riot gear slowly moved in.

The 32-year-old school cafeteria supervisor was shot during a traffic stop while reaching for his wallet, according to his girlfriend, who live-streamed video of the shooting's immediate aftermath on Facebook.
