Many singers and rappers are expressing their thoughts on the tragedy that struck the city of Boston as two explosions went off at the Boston Marathon's finish line around 3:15 p.m. on Monday, the Associated Press reports.

At least two people are dead and 23 others are injured. The Boston police commissioner reported that a third explosion went off at the JFK Library but there has been no injuries.

Cell phone service has been cut off in the city of Boston to "prevent any potential remote detonations of explosives."

The police also found two other bombs and dismantled them before they could cause harm.
