Four men who attacked a police station with samurai swords in Indonesia, killing a police officer, have been shot dead. The group rammed a minivan into police headquarters in the town of Pekanbaru before launching an attack. A fifth attacker was arrested as he tried to escape. The Islamic State terror group has claimed the attack via its news outlet. “When the car broke through into the Riau police headquarters, it was blocked by policemen,” police said at a televised news conference. “Then four of the men got out from the car and attacked police.” The incident comes after a spate of suicide attacks carried out by families, including children, shocked the country. Police blamed a local ISIS-inspired group, Jemaah Ansharut Daulah, for the attacks in the city of Surabaya.
