Spanish police have set up roadblocks and reinforced border checks as they hunt for the last remaining suspect in the attacks in Barcelona and Cambrils that killed 14 people and injured others.

Meanwhile, police have searched the home of a missing imam whom they say radicalised the suspects behind the attacks.

Officers say he may have died in a botched bomb-making operation on Wednesday.
