Role of Pakistan
Pakistan is Iran's neighbour, sharing borders of its Balochistan with Sistan and Baluchestan. Pakistan's Balochistan province is also suffering from low-level insurgency waged by terrorist and separatist militants against the government of Pakistan. These Pakistani Baloch terrorist and separatist militants groups are allied with Iranian Baloch groups. Iran and Pakistan historically have a strategic alliance fighting these groups. In February 2014 the two states signed a pact sharing responsibility for combating militants operating across the border. According to a former U.S. intelligence officer, Jundallah leader Abdolmalek Rigi was captured by Pakistani officials and delivered to Iran with U.S. support: "It doesn't matter what they say. They know the truth."
Claims of Central Intelligence Agency (CIA) support were debunked by a subsequent investigation showing that the CIA "had barred even the most incidental contact with Jundallah." The rumors originated in an IsraeliMossad "false flag" operation; Mossad agents posing as CIA officers met with and recruited members of Jundullah in cities such as London to carry out attacks against Iran. President George W. Bush "went absolutely ballistic" when he learned of Israel's actions, but the situation was not resolved until President Barack Obama's administration "drastically scaled back joint U.S.-Israel intelligence programs targeting Iran" and ultimately designated Jundallah a terrorist organization in November 2010. Although the CIA cut all ties with Jundallah after the 2007 Zahedan bombings, the Federal Bureau of Investigation (FBI) and United States Department of Defense continued to gather intelligence on Jundallah through assets cultivated by "FBI counterterrorism task force officer" Thomas McHale; the CIA co-authorized a 2008 trip McHale made to meet his informants in Afghanistan. According to The New York Times: "Current and former officials say the American government never directed or approved any Jundallah operations. And they say there was never a case when the United States was told the timing and target of a terrorist attack yet took no action to prevent it."Mashregh News, which has close ties to the IRGC, has accused Qatar for supporting both Jaish ul-Adl and Harakat Ansar Iran, alongside Saudi Arabia.Harakat Ansar Iran has made an appeal on Saudi Arabian websites for funding.
