TEHRAN (Reuters) - At least four people died in an apparent suicide attack in Iran's southeastern city of Zahedan on Thursday, Iranian news agencies said.
Two explosions, believed to be the result of a suicide attack, rocked the Grand Mosque in Zahedan, capital of Sistan-Baluchestan province, which borders Pakistan, and which has been hit by attacks blamed on the Jundollah Sunni Muslim rebel group.
"At least four people were killed in the first explosion," the semi-official Fars news agency quoted lawmaker Hosseinali Shahriari was quoted as saying. "We expect more casualties."
The official IRNA news agency said the explosions killed and injured a number of people, without giving precise numbers.
In May 2009, a suicide bomber killed 25 people and wounded more than 120 in an attack on a mosque in Zahedan.
In October 2009, 40 people, including 15 members of the elite Revolutionary Guards, were killed in a bomb attack in the province. It was the deadliest attack in Iran since the 1980s.
Iran hanged Jundollah's leader, Abdolmalek Rigi, last month.
