US officials believe the two suspects in the Boston Marathon bombings were planning to carry out further attacks before they were hunted down.
Following on from the capture of suspect Dzhokhar Tsarnaev, the Boston police have recovered a large amount of weapons and ammunition belonging to the brothers.
The news comes as federal prosecutors prepare charges against the surviving brother, who was captured Friday evening after a huge manhunt in the Boston area. If he is charged with using a weapon of mass destruction to kill people, he could face the death penalty.
Tsarnaev suffered gunshot wounds to the throat during the shootout, with Boston Police Commissioner Ed Davies saying that the 19 year old was in a critical but stable condition.
"The suspect is in critical but stable condition. There is a special interrogation team from theFederal Bureau of Investigation standing by to talk to him. That hasn't happened it. Until it does and until the investigation moves forward we won't know definitely what other things may come."
The other brother, 26 year old Tarmelan Tsarnaev, was killed during an earlier firefight with police, though police think that Dzhokhar may have killed his own brother after running him over when trying to drive away from the scene.
It is as yet unclear as to why the two carried out a terrorist attack at the Boston Marathon last week, in which 3 people were killed and more than 180 injured. One police officer was killed and another injured during the manhunt.
