TEHRAN -- There is evidence that proves that the U.S. and British forces in Afghanistan were behind the recent terrorist attack in southeastern Iran, Tehran’s ambassador to Kuwait said on Thursday.

On Sunday October 18, a terrorist attack killed over 40 people, including five senior commanders of the Islamic Revolution Guards Corps, in the southeastern province of Sistan-Baluchestan.The terrorist group Jundullah, which is also known as the Rigi group because it is led by Abdul-Malek Rigi, claimed responsibility for the attack, which was carried out in the city of Pishin, near the border with Pakistan.“There are documents and evidence proving that U.S. and British forces in Afghanistan had a hand in the incident,” Ambassador Ali Jannati told reporters at the Iranian Embassy in Kuwait City.These forces were in continuous contact with the terrorist cells and provided them weapons and financial support, he added.According to some other documents, the terrorist cells were also supported by Pakistan’s intelligence and security forces in Pakistan, he noted.Elsewhere in his remarks, Jannati said the United States overthrew Saddam Hussein’s regime and launched its campaign against the Taliban forces in Afghanistan to protect U.S. interests in the region and not to support Iran.“Of course we have taken advantage of the new situation, but (we) have documents that prove the U.S. and Britain supported these terrorist groups in Pakistan,” he added.He went on to say that some Iranians believe Saudi Arabia is supporting terrorist groups and a number of them recently held a demonstration in front of the Saudi Arabian Embassy in Tehran
