Multiple operations for Boston bomb victims

Doctors at the Boston Medical Centre where some of the victims of the Boston marathon bombs are being treated have given an update on their condition.

They say most of those admitted have undergone several operations.

Monday's twin bomb attack on the race finish line killed a boy of eight and two women, and injured more than 180.

US federal prosecutors are preparing charges against the surviving suspect Dzhokhar Tsarnaev.
