A group of armed attackers stormed a security post at a camp for Rohingya refugees in southern Bangladesh near the Myanmar border Friday, killing the post commander and looting weapons, police said. The attackers shot dead the commander and tied up other security personnel with ropes, before stealing 11 rifles and 570 rounds, local police chief Mujibur Rahman said. "The attack occurred at 2:20 am (2020 GMT) Friday. There were 10-15 attackers who were armed. They beat and then shot the Ansar (government security guard) commander of the camp from behind. He died on the spot," Rahman told AFP.
