Islamabad, 6 Nov. (AKI) - Pakistani security forces on Thursday arrested three Iranians suspected of planning a suicide attack which killed 42 people in Iran's southeastern region in October. The Sunni rebel group Jundallah (God's Soldiers) claimed responsibility for launching the attack that targeted Iran's elite Revolutionary Guards.

The attack in Iran's Sistan-Baluchistan province killed 15 Iranian Revolutionary Guards, including six senior commanders, and 27 others.

Three ethnic Baluch men were arrested by Pakistan's paramilitary Frontier Constabulary troops in a raid in Turbat, a district in Pakistan's Baluchistan province on the Iranian border, intelligence and paramilitary officials said.

The deadly explosion took place on October 18 during a unity conference between Sunni and Shia tribal leaders in the border city of Pishin.

Jundallah, or Soldiers of God, is also known as the Iranian People's Resistance Movement.

It is an insurgent Sunni Islamic organisation based in Baluchistan fighting for what it claims are the rights of Sunni Muslims in Iran.
