The 2005 Musayyib bombing was a suicide attack on a marketplace in Musayyib, Iraq, a town 35 miles south of Baghdad on July 16, 2005.

The attacker had detonated his explosive belt in a crowded marketplace, where hundreds of people had come to shop and mingle after the day's stifling heat subsided. The attack happened as a tanker containing cooking gas was passing, triggering an inferno that destroyed dozens of buildings, including a nearby Shia mosque where worshipers were emerging from evening prayers.
