Knifeman rams car into crowd at Parliament in London terror attack

A car mounted the pavement and ploughed into pedestrians crossing the busy Westminster Bridge beside London’s Big Ben.

Parliament has been placed on lockdown with MPs locked inside and armed police carrying shields protecting the building.

Reports suggest that 12 people have been injured and Scotland Yard said the attack is being treated as a “terrorist incident”.

A “police officer has been stabbed” and the “alleged assailant was shot by armed police”, Commons Leader David Lidington has told MPs.

Metropolitan police said they were called to a firearms incident on Westminster Bridge.
