Four migrants who entered the country illegally have been rescued after falling off a cliff, federal authorities in southern Arizona say.

Tucson Sector Border Patrol agents requested air support after arresting a group of migrants near Rio Rico early Friday, U.S. Customs and Border Protection officers say.

They say four people in the group fell off a cliff and two suffered broken legs, another had a broken pelvis and a fourth had a broken jaw.

A Tucson Air Branch helicopter airlifted the four to a landing zone where they were turned over to emergency medical services.

Their names and nationalities weren’t immediately available.
