The authorities in Iran have arrested the leader of the Sunni rebel movement Jundallah, which accuses the Shi'ite dominated goverment of discriminating against the country's Sunni minority.

Abdolmalek Rigi was reportedly arrested somewhere in the east of the country. Jundallah - which means soldiers of God - has claimed responsibility for the 18 October 2010 attack in which more than 40 people were killed. The victims included 15 members of the country's elite Revolutionary Guard. That attack was the most serious to have taken place since the 1980s.
