Boston bomb suspects 'were brothers'

The two Boston bomb suspects were brothers, according to their uncle.

Tamerlan Tsarnaev was killed in a gun battle with police in Massachusetts overnight. His younger brother Dzhokhar A Tsarnaev, 19, is on the run.

Three law enforcement officials, speaking on condition of anonymity, confirmed the bomb suspects were brothers.

The uncle, Ruslan Tsarni of Montgomery Village, Maryland, told The Associated Press the men lived together near Boston and have been in the United States for about a decade.

They travelled there together from their Russian home region near Chechnya.
