Iran has asked Pakistan to act against a terror group accused of carrying out the recent suicide bombing in the Iranian city of Chabahar that killed 36 people. The incident has caused fresh strain in ties between the two countries. Iranian Ambassador Mashallah Shakeri yesterday handed over a communique to Interior Minister Rehman Malik demanding Pakistan's cooperation in investigating the Chabahar suicide bombing that had also left over 100 people injured. The attack on a Shia procession on December 15 was claimed by the Sunni militant group Jundallah, Army of God. Iran has often alleged that Jundullah operatives are based and trained in Pakistan. Iranian authorities said they had caught one of the bomber's accomplices at the border, apparently trying to slip back into Pakistan. Malik assured the Iranian envoy that Pakistan would extend all help for the probe.
