Four illegal immigrants were rescued after falling off a cliff south of Tucson, federal authorities said.
Border Patrol agents detained a group near Rio Rico early Friday, U.S. Customs and Border Protection officers said.
They said 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 CBP helicopter airlifted the four to a landing zone where they were turned over to emergency medical services personnel.
In a separate incident Friday, a CBP helicopter was used to rescue a father and son who were camping on Mount Graham and failed to return from a hike.
They had been reported missing Wednesday by other family members who were camping with them at Riggs Lake.
About 40 search-and-rescue personnel from several agencies were called in to look for the two. They were found about 2 p.m. Friday.
Because of the rough terrain, the two had to be hoisted to safety by the CBP helicopter crew.
The 29-year-old father and 9-year-old son, who are from Tucson, were not hurt but suffered from dehydration.
