Sunni Islamist Baluch militants have claimed responsibility for the November 6 killing of a prosecutor in Iran's restive southeastern province of Sistan-Baluchistan.
The Jaish ul-Adl militant group said it killed Musa Nouri and his driver in revenge for the hanging of 16 prisoners on October 26.
The hangings were reportedly ordered by judiciary officials in retaliation for an attack in which the radical Sunni group had killed 14 Iranian border guards a day before.
Iranian authorities said they had arrested several suspects in connection with the assassination of Nouri, which occurred in Zabul, near the Afghan border.
Sistan-Baluchistan is home to a large community of minority Sunni Muslims, unlike the rest of Shi'ite-dominated Iran, and the province has long played host to drug traffickers and Sunni militants.
