Everything we know so far about the New York explosion

U S authorities were investigating on Monday night whether the New York bomb attacks were an Islamist terror plot as it emerged the alleged perpetrator had travelled to Afghanistan and Pakistan several times and showed signs of having been radicalised.

Ahmad Rahami, 28, was captured on Monday in a gunfight with police in the city of Linden, New Jersey, after an intense manhunt.

Two officers were shot and wounded when they responded to a tip from the owner of a bar that a man resembling Rahami – whose photo was widely circulated on television news channels – was hiding in the doorway.

Rahami, whose nickname was "Mad" - an abbreviation of his first name - was carried by stretcher into an ambulance, taken conscious to hospital and was undergoing surgery last night having been shot in the leg and shoulder.
