The province has a large, mainly Sunni Muslim ethnic Baluchi community which straddles the border and has long been a flashpoint, with Pakistan-based Baluchi separatists and jihadists carrying out cross-border attacks targeting the Shiite authorities.

"The terrorists tried to enter Chabahar police headquarters but they were prevented by the guards and they detonated the car bomb," he said.
