2 suicide bombers attacked Baghdad in Iraq on Thursday, killing almost 70 people, many of them Iranian pilgrims, police said.

The bombers, wearing vests stuffed with explosives blew themselves up in separate attacks that resulted to multiple deaths and injuries.

According to Reuters, the blasts occurred as apprehension grows in Iraq ahead of a pullout by U.S. troops from city centers in June, and after warnings from officials that insurgent groups may try to take advantage of that to launch attacks.

50 people were wounded and at least five children were among the dead.
