According to ABC News, the U.S. has been secretly and indirectly funding a group of Pakistani extremists who are actively engaged in terrorist activities in Iran.
Jundullah, which means Party of God in Farci (the equivalent of Hezbollah in Lebanon), is a Waziristan-based militant Islamic organization that has allied itself with Al-Qaida and presents a clear anti-Iranian agenda via its Iranian based operations.
ABC has uncovered proof that the U.S. is secretly funneling money and other forms of support to Jundullah via third party groups like Iranian exiles and Arab Gulf states.
Jundullah has been accused of, according to the ABC News, "an attack in February that killed at least 11 members of the Iranian Revolutionary Guard riding on a bus in the Iranian city of Zahedan.
As seen above, the aftermath of the bus bombing left utter devastation.
The U.S. denies any role in the affair.
