ST. PAUL, Minn. (AP) — A Martin Luther King Jr. Day march in St. Paul is causing some tense moments between police and protesters as well as disrupting light-rail and interstate traffic.

Hundreds of protesters tried Monday to march onto Interstate 94 in St. Paul but were diverted to side streets by a heavy contingent of Minnesota State Patrol officers. Interstate traffic was held back for a short time. Earlier, the march temporarily halted light-rail trains on a Minneapolis-to-St. Paul route.

The Black Lives Matter contingent was making its way toward the state Capitol. The marchers are using the rally to press a point about policing tactics they say have gone overboard and led to the deaths of young men in Minnesota and elsewhere.

Similar marches are scheduled in Chicago, New York City, Los Angeles.
