U.S. Air Force Maj. Fernando Ribas-Dominicci, killed in the 1986 U.S. air raid on Libya, was buried Sunday in his hometown in western Puerto Rico before thousands of mourners.

"Fernando's return to his homeland is the answer of the prayers of a mother who, during three years, asked Jesus Christ where her son was," his mother, Teresa Dominicci, said in an emotional address to 15,000 mourners who overflowed San Andres Cemetery under a burning Caribbean sun.Ribas-Dominicci, 33, piloted an Air Force F-111 fighter-bomber shot down in a U.S. strike on Libya April 15, 1986. The raid was in response to a West Berlin disco bombing 10 days earlier.
