[2] Zahedan is the capital of Sistan and Baluchestan province, shares a border with Pakistan and is the scene of frequent clashes between Iranian police and drug dealers, and militants and terrorists such as Jundallah.

[4] One day after the attack, Abdel Raouf Rigi, described as a spokesman for the Jundallah group, told Saudi-owned TV channel Al-Arabiya that a suicide bomber had targeted a secret meeting of Iran's elite Revolutionary Guards inside the Amir al-Momineen mosque.

[6] A spokesman for the Sistan-Baluchestan provincial judiciary said the three people "confessed to illegally bringing explosives into Iran and giving them to the main person behind the bombing".

Those who planned the crime wanted to undermine the Supreme Leader’s move to help build closer bonds between Shiites and Sunnis during his recent visit to Kurdestan.

[10] Jalal Sayah, deputy governor of Sistan and Baluchestan Province, accused the United States of sponsoring terror and hiring mercenaries to attack Iran.

Several sources such as the ABC News, Daily Telegraph, and journalist Seymour Hersh have also reported that Jundullah has received support from the United States against Iran.
