Police in Iran have arrested 40 suspects after the twin bombings of a mosque in the south-eastern city of Zahedan.


The blasts killed 27 people outside a mosque on Thursday. A Sunni insurgency called Jundallah claimed responsibility.


Jundallah, which says it is fighting for the rights of the mainly Sunni Baluchi minority, said the attack was revenge for the execution of its leader Abdulmalik Rigi in June.
