WASHINGTON (AP) - Hundreds of law enforcement officers from around the country are expected to attend a Mass being held in Washington ahead of National Police Week.

The Annual Blue Mass will be held Tuesday at St. Patrick's Catholic Church in Washington. The Mass honors law enforcement and first responders. Some streets in the area will be closed from 9 a.m. to 2 p.m.

Washington's Archbishop, Cardinal Donald Wuerl, will celebrate the Mass, which will include an honor guard, bagpipers and the playing of taps in honor of law enforcement officers who died in the past year.
