Mexico's federal Education Department is recommending local officials be fired for not preventing sex abuse at a Mexico City school for young children.

The department says city education officials didn't act quickly enough after a complaint was filed in early December.

Another half-dozen complaints by parents surfaced, but the school wasn't hit with a closure order until April.

The department says in a statement Friday that "it is clear authorities acted with laxness, and a lack of speed, diligence and skill in responding to the complaint."

Parents of the students aged roughly 3 to 5 say their children told them they had played sexually oriented games with the husband of the school's director.

The department said the school should be closed permanently.
