The President of Iran Mahmoud Ahmedinejad has blamed Pakistan-based elements for a suicide attack that killed 42 people in Sunni-majority Sistan-Baluchistan province yesterday. He also asked Islamabad to help bring the perpetrators to justice. Iran's foreign ministry summoned the Pakistani charge d'affaires in Tehran and told him that the perpetrators of this attack came to Iran from Pakistan. Iran's state-run media reported that Sunni militant group Jundallah (God's soldiers) had claimed responsibility for the attack. Iran's Interior Minister Mustafa Muhammed Najjar too took up the matter with his Pakistani counterpart Rehman Malik during a phone conversation. Jundallah's activities have emerged as an irritant in Pak-Iran ties. Iranian officials have complained on several occasions that Jundallah operatives are active in Pakistan's southwestern Balochistan, which borders Sistan-Baluchistan. Pak Foreign Office spokesman Abdul Basit denied the attack was planned in Pakistan but said authorities are looking into the matter.
