Two government officials tell The Associated Press that U.S. intelligence agencies added the Boston bombing suspects' mother to a federal terrorism database about 18 months before the attack....

The mother of the Boston Marathon bombing suspects insisted Thursday that her sons are not responsible for the attack and said she did not see any aggression in the older brother, even when the FBI questioned him two years ago.

The F.B.I. and the C.I.A. separately had Tamerlan Tsarnaev, the suspect who died last week, listed in government databases in 2011, though they cleared him of extremist links.

The FBI has flatly rejected an assertion by the mother of the two suspected Boston bombers that the bureau had been tracking her oldest son and had spoken with him last week after the deadly marathon bombing.

The FBI released photos and video Thursday of two suspects in the Boston Marathon bombing and asked for the public's help in identifying them, zeroing in on the two men on surveillance-camera footage less than three days after the deadly attack.

Federal investigators want to speak with multiple persons seen in at least one video from the Boston Marathon, according to Department of Homeland Security Secretary Janet Napolitano, backing up what FBI sources had told Fox News earlier.

The FBI said Monday it believes it knows who was behind one of the most significant art heists in the United States -- the 1990 theft of 13 precious works, once valued at $500 million, from Boston's Isabella Stewart Gardner Museum.

A domestic dispute was likely at the root of a bomb scare that forced a Boston-to-Chicago flight carrying 83 passengers to land in Buffalo on Monday, but the FBI says there was never a real threat.

U.S. authorities were searching two locations in the Boston area in connection with the attempted bombing in Times Square on May 1, an FBI spokesman said on Thursday.
