HRANA News Agency reports that according to Press TV, the attack occurred in front of Imam Hussein Mosque in southeastern city of Chabahar when people gathered for a mourning ceremony on the religious occasion of Tasua. The Shia religious holiday was overshadowed by the suicide bombing that killed 41 people and injured several more. Although the rebel group Jundollah claimed responsibility for the deadly attack, Chief of Iran’s Parliament National Security and Foreign Policy Commission Alaeddin Boroujerdi accused the United States and Britain of involving in the attack, ISNA news agency reported.

U.S. President Barack Obama condemned the suicide bomb attacks on Wednesday as a “despicable offense” and said those who carried them out must be held accountable.
