An international manhunt has been launched by French police for man who is believed to have been involved with the Paris attacks. Abdeslam Salah is one of three brothers believed to have been involved in the coordinated attacks which left 129 dead and hundreds more injured on Friday, 13 November.

One of Salah's brothers is believed to have died during the attacks. A third was arrested in Belgium.

French police issued an international arrest warrant for the "dangerous" 26-year-old, advising the public not to approach him. Salah is described as having brown hair, and 5ft 7in tall (170cm).

He is believed to have rented the black Volkswagen Polo used by the group of terrorists who attacked the Bataclan concert hall, killing at least 89 people.

British security services are reportedly working with counterparts in France and Belgium to identify and pursue those behind the massacre and security. Security has been increased in UK cities and ports.

Earlier today, Theresa May urged Britons to remain vigilant, although the terror threat level has not been changed from the second-highest "severe" rating.
