Iran executed a brother of the detained leader of a Sunni Muslim rebel group behind the deadliest bomb attack in the Islamic Republic in years, official media reported.
Abdolhamid Rigi, a convicted member of Jundollah (God's Soldiers), was hanged in a prison in the southeastern city of Zahedan, after his execution was postponed last July and again in December in order to get more information from him.
Predominantly Shi'ite Muslim Iran seized his brother, Jundollah leader Abdolmalek Rigi, in February -- four months after the group claimed a bombing which killed dozens of people, including senior officers of the elite Revolutionary Guards.
Families of Jundollah victims were present at the execution to help alleviate "their pain," said judiciary official Ebrahim Hamidi in Sistan-Baluchestan province.
"The judiciary decided not to carry out the sentence in public because of some security issues," he said.
State Press TV said Abdolhamid Rigi was charged with bombing operations, armed robbery and drug trafficking.
