Iran ? Police and insurgents clashed after a bombing in southeastern Iran late Friday near the site where an explosion killed 11 members of the elite Revolutionary Guards this week, Iranian news agencies reported.

“Minutes ago, the sound of a bomb explosion was heard in one of Zahedan’s streets,” the state-run news agency IRNA said, without giving more details.

The semiofficial Fars news agency said clashes broke out between Iranian police and armed insurgents after the explosion.

Fars quoted the governor of Zahedan, Hasan Ali Nouri, as saying the blast was a “sound bomb explosion”- a device that creates a loud boom but that usually does not cause casualties.

On Wednesday, a car bomb blew up a bus carrying Revolutionary Guards, killing 11, in Zahedan, capital of Sistan-Baluchestan province, which sits on the border with Pakistan.
