LONDON (Reuters) - Loud bangs similar to gunfire were heard outside Britain's parliament on Wednesday and two people were seen being treated inside the gates by medical staff, according to a Reuters witness.

 

A parliamentary clerk told Reuters two people had been shot, but there was no official confirmation from the police. A Reuters photographer said he saw at least a dozen people injured on Westminster Bridge near the parliament building.
