Tube Station Stabbing 'A Terrorist Incident'

The stabbing of three people at a London tube station by a man wielding a large knife is being treated as a "terrorist incident", the Met Police has said. The suspect apparently shouted "this is for Syria" before attacking members of the public near the ticket barriers at Leytonstone station. Video footage obtained by Sky News shows police officers trying to subdue the suspect with a taser several times before they successfully bring him to the ground.
