A pair of suicide bomb blasts outside a mosque in Iran killed at least 30 people and wounded more than 100 on Wednesday during a Shi'ite mourning ceremony, local media reported.   

Al Arabiya television reported that Jundollah, a Sunni Muslim rebel group, had claimed responsibility for the attack outside the Imam Hussein Mosque in the southeastern city of Chabahar, near Iran's border with Pakistan and Afghanistan.

The report could not be confirmed independently.   

"Terrorists carried out two suicide bombings among Shi'ite mourners in front of a mosque in the town of Chabahar," deputy Interior Minister Ali Abdollahi told Iranian radio. 

Iran has faced a string of blasts in past months, including two in June that killed 27 people in the same province. Jundollah had also claimed responsibility for that attack.

The Sistan-Baluchestan province is an impoverished area near Pakistan and Afghanistan. Bombings and clashes between security forces, ethnic Baluch Sunni insurgents and drug traffickers have increased in recent years in the area.

Ali Mohammad Azad, governor of Sistan-Baluchestan province, put the death toll in the mosque blast at "over 30". "Many women and children were killed in the suicide bombing," he told state television.   

Ali Bateni, governor of Chabahar, said two assailants were involved. "One of them was killed and the other was arrested," he said.

Mahmoud Mozafar, head of the province's Red Crescent, said his team had received a number of threats before the ceremony. "We were on alert in the past days because of some anonymous threats," he told Reuters by telephone.       

He said that according to his information more than 36 people were killed. - Reuters
