Residents have described the terrifying scenes in Watertown at a shootout between the two Boston marathon terror suspects and police, which left one officer dead.
One of the terror suspects died in hospital from gunshot wounds after police shot at a moving vehicle which was carjacked with a hostage inside.
It is believed the two suspects held a hostage for half an hour while police pursued the car to Watertown, where explosives were thrown from the car at police and gunfire was exchanged, a statement said.

'A second suspect was able to flee from that car and there is an active search going on at this point in time,

He told NBC: 'I was sitting in the living room and started hearing gunfire outside our apartment. I went to the window and saw two people behind a black Mercedes S.U.V. and a Sedan right next to it.
'About 70 or 80 yards down the street was six police vehicles. They were engaged in gunfire for a few minutes, they were also utilising bombs and what looked like grenades and a pressure cooker bomb.
'It was a firefight. There was a long exchange of gunfire and shooters had hand guns.'
He described how the fight came to a climax when one of the suspects was 'taken down' and the other escaped in a car.
'The Sedan was parked easterly on Laurel Street and the S.U.V. to the west, separated by 10ft. They were in between to two cars taking cover behind the Mercedes shooting westwards.
'When they utilised their larger bomb they threw it towards the officers as a decoy. It covered the street with smoke.
'One ran towards the cops, the other one got back into the S.U.V. The one running towards the officers was taken down.
'The second shooter got into the S.U.V, turned it around and went full speed towards the police officers, went through the middle between the cop cars taking off the doors and breaking through.'
Peter Jennings, 33, said he woke to the sound of an explosion just before 1am at home on Prentiss Street in Watertown.
‘It sounded like a stick of dynamite went off. I looked out the window, and it was like nothing I’ve ever seen – blue light after blue light after blue light.’
He said the air smelled like ‘at the end of a fireworks show, like a wick smell.’
‘I had a bad feeling because of what happened on Monday,’ he added.
