Jundallah is a militant Moslem organisation based in the Balochistan region in Pakistan, and it is said to be run by the CIA and its friends.
On 23 February 2010 Iran arrested Jundallah's leader Abdol Malek Rigi, a 'terrorist backed by the USA UK and Israel', after police boarded a civilian flight
Reportedly, Pakistan helped Iran nab the Jundallah chief
Iran state media said Rigi had been on board a flight from Dubai to Bishkek, the capital of Kyrgyzstan.
Dubai has trade ties with Iran.
Bishkek airport confirmed that Kyrgyzstan Airways flight QH454 from Dubai had been told to land by Iran.
Iran's intelligence minister, Heydar Moslehi, claimed that Rigi had been at a US base in Afghanistan 24 hours before his arrest.
At a press conference he has shown a photograph which he said showed Rigi outside the base.
Photographs were shown of an Afghan passport and identity card said to have been given by the Americans to Rigi.
Iran's intelligence minister alleges that Rigi met the then Nato secretary-general, Jaap de Hoop Scheffer, in Afghanistan in 2008, and had visited European countries.
Allegedly, the USA wants to break up Pakistan and Iran along ethnic lines.
Iran claims that Jundullah, which has carried out a series of bombings, is backed by Britain, Israel and America.
It has also been alleged by western media, including The Sunday Telegraph, that in 2007 the CIA provided funding and weapons to Jundullah.
Jundallah's most serious attack, in 2009, killed two generals of Iran's Revolutionary Guard.
In 2009, Jundallah blew up an Iranian mosque killing 25 people.
Rigi's brother, Abdol Hamid Rigi, said he had received money from the United States.
It appears likely that "the conflict between the Pasdaran (Iran's revolutionary guards) and Jundullah (CIA backed group) depends on the struggle for control of the opium trade". (Tehran arrests a Sunni militant linked to al Qaeda)
