Gunmen attack Iranian shrine and parliament building

Gunmen and suicide bombers attacked Iran’s parliament and the shrine of its revolutionary leader on Wednesday, killing at least 12 people, wounding dozens and igniting an hours-long siege at the legislature that ended with four attackers dead.

The Islamic State group claimed the attacks, marking the first time the Sunni extremists have taken responsibility for an assault in Shiite-majority Iran. The militants are at war with Iranian-backed forces in Syria and Iraq, and view Shiites as apostates.

The attacks began midmorning when assailants armed with Kalashnikov rifles stormed the parliament building. One of the attackers later blew himself up inside, where a session had been in progress, according to a statement carried by Iran’s state TV.

Deputy Interior Minister Mohammad Hossein Zolfaghari told Iran’s state TV the apparently male attackers wore women’s attire. The semi-official Tasnim news agency later reported the siege had ended with four of the attackers killed.

Mizan Online, an Iranian state-run news website, said 12 people were killed and 42 wounded in the two attacks. It quoted Pirhossein Kolivand, the head of Iran’s emergency department. (AP)
