Tsarnaev Brothers

U.S. Looking for 'Persons of Interest' in Boston Attack Probe

Investigators are pursuing other "persons of interest" possibly linked to the Boston Marathon bombings, U.S. lawmakers say.

Russian authorities wiretapped the mother of the Boston bombing suspects and recorded her discussing jihad in 2011.

Surviving suspect in Boston bombing says his older brother led the attack, ‘wanted to defend Islam.’

Older Tsarnaev brother, now dead, may be connected to a gruesome murder of 3 – of whom 2 were Jews.

FBI affidavit reveals Boston bomber's chilling words to the man whose car he hijacked.

Britain's The Mirror quotes security source: "We have no doubt the brothers were not acting alone."

Boston terrorists were Muslims from the Caucasus area, near Chechnya. Not much else is known yet.

First suspect killed in Watertown shootout early Friday morning. Second nabbed Friday evening.
