London attack: Second person confirmed dead in Westminster terror incident

A second person has died following a suspected terror attack outside Parliament.

This follows the death of a woman and a number of others, including a police officer, who have been injured, according to a junior doctor at St Thomas' Hospital. Some victims have been described as having "catastrophic'' injuries.

Proceedings at Parliament were suspended after a police officer was stabbed and an alleged assailant shot by armed police outside the Houses of Parliament, shortly after a vehicle is reported to have mowed into members of the public on Westminster Bridge.

Police are treating the Westminster shooting which took place on Wednesday afternoon as a terrorist incident until further notice but details of the attack remain unclear.

Staff inside parliament found themselves on lockdown and unable to leave the building after at least three gun shots were heard by those inside the Houses of Parliament.

Early reports suggest the vehicle, which mounted the pavement on Westminster Bridge and ploughed into approximately a dozen people, was the same vehicle which then rammed into the gates of Westminster just around the corner.

Theresa May was in parliament at the time of the incident but was quickly confirmed safe.

Proceedings at the House of Commons have been suspended and the Speaker said Parliament will stop activity until further notice.

Commons leader David Lidington, announced the commons would be suspended in the house, as ambulances and other emergency vehicles dominated scenes.
