MEXICO CITY (AP) — The attorney generals from the United States, Mexico, Guatemala, El Salvador and Honduras have agreed to form a high-level group to address the migration of unaccompanied children.

U.S. Justice Department spokesman Brian Fallon says in a statement that Attorney General Eric Holder met with his counterparts in Mexico City on Tuesday.

The attorney generals will form the group with prosecutors from each country, and will work on a strategy to handle the flow of child migrants. The group is to meet in the coming weeks.

Since Oct. 1, the United States has detained more than 66,000 unaccompanied child immigrants, mostly from Honduras, El Salvador and Guatemala. More than 66,000 additional immigrants traveling as families, mostly mothers and young children from Central America, have also been caught.
