Anti-terror police search house after Syria bomb
Footage has emerged of what is believed to be the first suicide bombing by a Briton in Syria.
Anti-terror police are searching a house in Crawley, in West Sussex, thought to be the home of a man known as Abu Suleiman al-Britani, as part of an investigation into the truck bombing in the city of Aleppo last week.
The attack on a prison in the city resulted in inmates escaping.
