LONDON (AP) – A vehicle mowed down pedestrians on a bridge and the attacker then stabbed a police officer outside the British Parliament. At least four people died, including the attacker and a police officer.

Conservative parliamentarian and Foreign Office minister Tobias Ellwood, whose brother was killed in the Bali terror attack in 2002, performed mouth-to-mouth resuscitation on the police officer who was stabbed and later died.

About 10 yards away was the attacker who was shot dead by police after scaling the security wall toward Parliament’s grounds.

Ellwood, who served in the British military and served in Bosnia, Northern Ireland, Kuwait and Cyprus, applied pressure to the police officer’s multiple lacerations.

Photographs showed Ellwood’s bloodied hands and face from the police officer’s wounds while the alleged attacker was seen nearby.

Ellwood has been an undersecretary at the Foreign Office since 2014, covering the Middle East and Africa.
