The Shiite mosque that was bombed yesterday in Iran killed 23 and injured more than 100 others.
The New York Times reported:
The bomb went off at 7:45 p.m. at Ali-ibn-Abitaleb, the second largest Shiite mosque in the city. ISNA said the bomb had been hidden in a bag in the men’s section of the mosque.

No group immediately took responsibility for the attack. An armed opposition group called Jundullah has carried out similar attacks in the region in the past, including one on a bus carrying members of the Revolutionary Guards in 2007. The group says it is fighting discrimination against Sunnis by Iranian authorities. Iran says the group is a terrorist organization with ties to Al Qaeda.
But a new report from al-Arabiya says that Iran captured three of the operatives who reportedly claimed that the U.S. hired them to bomb the mosque.
A top Iranian official accused on Friday United States intelligence services of hiring the bombers who carried out a devastating attack on a Shiite mosque in the southeastern city of Zahedan, Fars News Agency reported.
"Three people involved with the terrorist incident were arrested," Jalal Sayah, deputy provincial governor of Sistan-Baluchistan province, told the agency.
"According to the information obtained they were hired by America and the agents of the arrogance."
Love the idea of "agents of arrogance" but how seriously are Iranian officials taking this?
