Former head of Pakistan's Inter-Services Intelligence (ISI) agency Hamid Gol says the United States is seeking to create and train terrorist groups in the region.

In a Wednesday interview with Fars news agency, Gol said Washington had been making efforts to destabilize the region through supporting groups like the Pakistan-based Jundallah terrorist group.

Gol went on to say that such attempts by the US intelligence agencies were in particular directed at fomenting unrest in Iran.

"The US intelligence agencies pursued just one goal by forming Rigi's group which was provoking unrests and instability in Iran," Gol was quoted as saying.

He also accused Washington and its western allies of seeking to strain ties between Iran and Pakistan.

The remarks come days after Iranian security forces arrested Jundallah ringleader Abdolmalek Rigi while he was aboard a Kyrgyz airliner on a flight from the United Arab Emirates to Kyrgyzstan.

In his confession broadcast by Press TV in late February after his arrest, Rigi talked about offers of unlimited support by the US spy agency, the CIA, saying the Americans offered to "cooperate with us" and "promised to give us a base along the border with Afghanistan near Iran."

Rigi's group has claimed responsibility for numerous terrorist attacks in Iran. The group has carried out murder, armed robbery, kidnappings, acts of sabotage and bombings inside Iran.
