A Spanish missionary priest being treated for Ebola died Tuesday in a Madrid hospital, authorities said.

Spain's Health Ministry said a day earlier that it had obtained a course of the U.S.-made experimental Ebola drug ZMapp to treat Father Miguel Pajares, 75.

Pajares died Tuesday at Carlos III Hospital, the hospital and his order said. The hospital would not confirm that he had been treated with the drug, but his order said earlier that he would be.

He is one of only three Ebola patients thought to have received the experimental drug. The others are two Americans evacuated to Atlanta.

Pajares, who was treating people with Ebola at the San Jose de Monrovia Hospital in Liberia when he became infected, was evacuated to Spain on Thursday. He worked for the San Juan de Dios hospital order, a Spain-based Catholic humanitarian group that runs hospitals around the world. (Yonhap)
