Witness describes Boston gun battle
An eyewitness has described the dramatic shootout between the police and the Boston bombing suspects.
Tamerlan Tsarnaev was killed during the police manhunt last Friday, while his brother Dzhokhar Tsarnaev was captured later that day and remains in hospital with serious injuries.
Andrew Kitzenberg told the BBC's Ian Pannell how he filmed events from his bedroom window - and how a bullet pierced his wall.
