The killing in Normandy was the first known attack claimed by ISIS inside a church in the West after compiling a hitlist of places of Christian worship.
It comes as ISIS warned that London and Washington DC are next on the list of target cities, with images threatening major world capitals being posted online.
Adel Kermiche (pictured right and left, in 2011), 19, has been named as one of the two ISIS knifemen who stormed into a church in Normandy and cut the throat of an 84-year-old Catholic priest Jacques Hamel before being shot dead by police
A French policeman cordons off the area around the body of one of the two knifemen. Parisian prosecutor Francois Molins revealed that the pair were carrying a fake bomb with a timer, a handgun and knives during the attack and said they used nuns as human shields
Father Jacques Hamel had his throat cut in the attack that also left a nun critically injured. He was at the church because he was filling in for the local priest who was on holiday
