Obama to hold moment of silence for Boston victims

WASHINGTON (AP) -- The White House says President Barack Obama will observe a moment of silence Monday to honor the victims of the Boston Marathon bombings.

Obama will pay tribute to the victims at 2:50 p.m. Monday, the time the first of two bombs exploded last week near the marathon finish line. The president will mark the moment privately at the White House, with no press coverage.

Massachusetts Gov. Deval Patrick has also asked his state's residents to observe a moment of silence Monday afternoon. Bells will toll across the state after the minute-long tribute to the victims.
