Boston bombing trial set to open

The trial of the only suspect in the Boston bombings begins Monday with jury selection, 20 months after the attack that turned the city's annual marathon into a scene of carnage.

The jury selection that begins Monday is expected to last at least two weeks and 1,200 people have been summoned for the process.
