Four men charged with conspiracy to murder in the failed 21 July London attacks have been remanded in custody.

Bomb suspects Muktar Said Ibrahim, 27, Yasin Hassan Omar, 24, and Ramzi Mohammed, 23, appeared before Bow Street magistrates at Belmarsh prison.

The charges faced by Manfo Kwaku Asiedu, 32, relate to an unexploded device found in a park two days after the attacks on three Tubes and a bus.

The four men will next appear at the Old Bailey on 14 November.

Armed police stood guard outside the court as the accused arrived for the hearing in police convoys.
