Mexican prosecutors say they have freed two children held by pimps who used their hold over the children to force their mothers into prostitution in the United States.

The raid announced Tuesday appears to confirm one of the most chilling allegations about the prostitution trade operated by organized gangs in central Mexico: that some women are forced into sex for hire because they fear their children will be harmed if they rebel or attempt escape.

The raid occurred last week in the town of Tenancingo, the pimps' stronghold.

The Attorney General's Office said the children's mothers had been forced to prostitute themselves in Texas and New York.

Though the office did not give the children's ages, an activist familiar with the case said they were girls aged 6 and 9.
