Two suicide bombers targeted a Shiite mosque in Baghdad on Tuesday, one blowing himself up at a nearby checkpoint while the other slipped inside during prayers.
The blasts killed 29 people, Iraqi officials said.
The coordinated bombings were the latest in a string of attacks to hit Iraq, reviving fears the country is headed back toward the widespread sectarian bloodshed that pushed it to the brink of civil war in 2006 and 2007.
Two police officers said the first bomber detonated his explosives at a security checkpoint near the mosque in Baghdad’s northern Qahira neighbourhood in an apparent attempt to distract the authorities. The area is a middle-class, Shiite-majority neighbourhood.
Amid the commotion, a second bomber slipped past concrete blast walls and into the mosque, where he blew himself up while worshippers were performing midday prayers, according to police officials.
The bombings also wounded 55 people, the officials said. Most of the casualties were students from the nearby Imam al-Sadiq University for Islamic Studies. Police officials said the university’s Shiite students usually perform their midday prayers in the mosque that was hit.
After the blasts, security forces quickly sealed off the area around the simple, unadorned mosque.
A medic in a nearby hospital confirmed the casualties. All officials spoke on condition of anonymity because they are not authorized to speak to media.
There was no immediate claim of responsibility, but suicide bombings and attacks against Shiite worshippers are frequently the work of al-Qaida’s Iraq arm. Sunni extremists such as al-Qaida consider Shiites to be heretics and want to undermine Iraq’s Shiite-led government.
Tuesday’s bombings follow a string of attacks on Sunni mosques that killed more than 100 worshippers between mid-April and May.
The bloodshed roiling Iraq has risen to levels not seen since 2008. Nearly 2,000 have been killed since the start of April, including more than 220 this month.
On Sunday, a wave of apparently coordinated bombings and a shooting killed at least 51 people. Fifteen people were killed in bomb attacks on Monday, including one caused by a suicide bomber who set off his explosives-laden belt among a group of policemen in Fallujah, west of Baghdad.
