WATERTOWN, MASS. - One of two suspects in the Boston Marathon bombing is dead and a massive manhunt is continuing for another, authorities said early Friday.
The two have been identified as Dzhokhar A. Tsarnaev, 19, of Cambridge, Mass., and his brother, Tamerlan Tsarnaev, 26.
In a long night of violence, the two killed an MIT police officer, injured a transit officer in a firefight, and threw explosive devices at police during their getaway attempt, authorities said.
Boston Police Commissioner Edward Davis says the suspect at large, Tamerlan Tsarnaev, is the one seen in the white hat in images of the Boston Marathon suspects released by the FBI Thursday. Davis says he is "armed and dangerous."
Davis said all of Boston must stay in their homes as the search for the surviving suspect in the marathon bombings continues. Public transit in the area has been suspended. Amtrak service was also temporarily suspended between Boston and Providence, R.I. The FAA has also imposed temporary flight restrictions in the Boston area.
In addition, all taxi service in the City of Boston has been suspended pending further notice.
The Middlesex district attorney said the two men are suspected of killing a Massachusetts Institute of Technology police officer on campus late Thursday, then stealing a car at gunpoint and later releasing its driver unharmed. Hours earlier, police had released photos of the marathon bombing suspects and asked for the public's help finding them.
Authorities say the suspects threw explosives from the car as police followed it into Watertown. The suspects and police exchanged gunfire, and one of the suspects was critically injured and later died while the other escaped.
Residents throughout the Boston area -- including Watertown, Cambridge, Waltham, Newton and Belmont -- have been advised to keep their doors locked and not let anyone in. The Boston Police Department warned residents to "stay home." Vehicles were barred from entering or leaving Watertown.
Police are evacuating residents in Cambridge who lived on the same block as the suspects, going door-to-door telling people to leave. Police told CBS News it is just a precaution, but they have roped off the area and residents are coming out with suitcases.
At one suspect's apartment building, on Norfolk Street in Cambridge, a CBS News producer at the scene witnessed a woman being taken away authorities, being dragged by her arms. It was not known if she was being arrested or resisting being evacuated.
Some time after police evacuated everyone from the premises, police yelled "Fire in the hole," and detonated something.
A law enforcement official tells CBS News the two suspected bombers have been identified. They are believed to be from Chechnya or near Chechnya. They are legal permanent residents of the U.S. They are not students.
Tamerlan -- the suspect seen in FBI photos released Thursday as wearing the black hat -- was wounded in an exchange of gunfire with police during last night's pursuit. He was captured and rushed to Beth Israel Deaconess Medical Center in Boston, where he died at 1:35 a.m. Doctors said he had gunshot wounds and a blast injury.
The wounds were throughout the trunk of the man's body, CBS Station WBZ reported.
Ruslan Tsarni, an uncle of the suspects, told CBS Station WBZ "it absolutely devastated me," upon learning that his nephews had been named a suspect in the Marathon bombing. "It's not comprehendable, in our family."
Tsarni told WBZ that his nephews had immigrated to the United States around 2000 or 2001, and have lived in Cambridge since that time.
According to Tsarni, Dzhokhar completed high school in Cambridge. Tsarni, who says he hasn't been in touch with the brothers since around 2009, told the station he believes that the brothers' parents may have moved back to Russia.
Informed of the unfolding situation that left Tamerlan Tsarnaev dead in a shootout, Tsarni said, "He deserved his. He absolutely deserved his. . . . They do not deserve to live on this earth."
Alvi Tsarni, another uncle of the suspects, told CBS News said he was shocked about learning news of his nephews. "It's not possible. My nephews can't do this stuff, there's no way," he said.
He also said that Tamerlan's wife is an American, a Christian who had recently converted to Islam.
President Obama was briefed on the situation overnight, according to a White House official.
The MIT shooting on the Cambridge campus Thursday night was followed by gunfire and explosions in Watertown, about 10 miles west of Boston.
The MIT officer had been responding to report of a disturbance Thursday night when he was shot multiple times, according to a statement from the Middlesex district attorney's office and Cambridge police. It said there were no other victims.
In Watertown, multiple gunshots and explosions were heard at about 1 a.m. Friday. Dozens of police officers and FBI agents were in the neighborhood and a helicopter circled overhead.
State police spokesman David Procopio said, "The incident in Watertown did involve what we believe to be explosive devices possibly, potentially, being used against the police officers."
An MBTA police officer was shot and seriously wounded. Officer Richard Donohue, Jr., 33, was rushed to Mount Auburn Hospital in Cambridge, where he is in critical condition, reports WBZ.
Boston cab driver Imran Saif said he was standing on a street corner at a police barricade across from a diner when he heard an explosion.
"I heard a loud boom and then a rapid succession of pop, pop, pop," he said. "It sounded like automatic weapons. And then I heard the second explosion."
He said he could smell something burning and advanced to check it out but area residents at their windows yelled at him, "Hey, it's gunfire! Don't go that way!"
MIT said right after the 10:30 p.m. shooting that police were sweeping the campus in Cambridge and urged people to remain indoors. They urged people urged to stay away from the Stata Building, a mixed-use building with faculty offices, classrooms and a common area.
Hours later, MIT, which has about 11,000 students, said the campus was clear but the shooter was still on the loose.
