Iran arrests three linked to terrorist attack

Iran has arrested three suspects in connection with a terrorist attack in the southeastern province of Sistan-Baluchestan, Fars News Agency reports.

The provincial governor was quoted as saying by Fars that he could not disclose the identity of the detained individuals 'for security reasons'.

The three suspects were the first to be arrested after Sunday's bombing, which occurred in Pishin, a borderline region in southeastern Iran. The attack left at least 42 people including two senior military commanders dead.

Pakistan-based Jundullah terrorist group has claimed responsibility for the attack.

Provincial officials said on Tuesday that gunmen killed two police officers in separate attacks in the city of Iranshahr, Mehr News Agency reported.

It is not yet clear whether the killings were in connection with Sunday's suicide attack.
