Abdolmalek Rigi, ringleader of the Pakistan-based terrorist group of Jundallah, has been captured in eastern Iran, Press TV reported.
Rigi was reportedly captured on a flight from Dubai to Kyrgyzstan. Jundallah's number two man was also arrested.
No further details are available.
The Jundallah group has claimed responsibility for numerous terrorist attacks in Iran. The group has carried out mass murder, armed robbery, kidnapping, acts of sabotage and bombings. They have targeted civilians and government officials, as well as all ranks of Iran's military.
In their latest attack, which occurred on October 18, more than 40 Iranians - among them 15 members of the Islamic Revolution Guards Corps (IRGC), including top commanders, in addition to several tribal elders - lost their lives when Jundallah terrorists carried out an operation in the border region of Pishin, located in Iran's southeastern province of Sistan-Baluchestan.
Citing US and Pakistani intelligence sources, the news group of an American televison network, ABC, reported in 2007 that the terrorist group "has been secretly encouraged and advised by American officials" to destabilize the government of Iran.
Investigative journalist Seymour Hersh revealed in another report in July 2008 that US Congressional leaders had secretly agreed to former President George W. Bush's USD 400 million funding request, which gave the US a free hand in arming and funding terrorist groups such as Jundallah militants.
The Pakistan-based terrorist organization denies having any link to Washington but Rigi's brother, arrested earlier, confirmed in an interview with Press TV that the Jundallah leader had, in fact, established links with US agents.
Abdulhamid said that in just one of his meetings with US operatives, his brother had received USD 100,000 to fuel sectarianism in Iran.
