According to the Centre for Research on Globalization:
Explosive devices and arsenals used in a terrorist attack in the southeastern Iranian city of Zahedan on Wednesday came from the United States, the semi-official Fars news agency reported on Saturday.
Relevant documents, photographs and film footage, which show that the explosives and arsenals used in the attack were American, would soon be made public, an "informed source" was quoted as saying.
The source further pointed out that Jundallah, a shadowy Sunni militant group, had several plots for assassinating Sunni and tribal leaders to sow discord and foment conflicts between the Shiite and Sunni citizens in Sistan-Baluchestan province.
On Wednesday morning, an explosive-laden car exploded in Zahedan as a bus, belonging to ground forces of Iran's Revolutionary Guards Corps, passed by, killing at least 11 people and injuring 31 others.

Terrorist attacks in Iran and Iraq point to the U.S. and Britain
The U.S., not Iran, is wrongfully "meddling" in Iraq
It's hard to read between the lines, but I'm trying to figure out what their agenda is. Here is my favorite quote from the website:
"The US and Britain, which allege to be pioneers in the campaign against terrorism, are themselves actually defending the terrorists, training them and providing them with the needed media and financial supports and facilities." (Soltan-Ali Mir, Iranian Interior Ministry)
