TEHRAN, Iran (AP) -- Iran's official IRNA news agency says a gas explosion in a residential building has killed six people and wounded 11.


The Wednesday report says the explosion in the southeastern city of Ahvaz destroyed four units in the building and damaged neighboring homes.


Authorities have blamed a string of recent accidental explosions on disregard of safety regulations. Earlier this month, a blast in an upholstery foam factory in the southern Iranian city of Shiraz killed one person and injured five others.
