The family of a Boston pastor abducted in Egypt is appealing to his captor to release the 61-year-old man, saying he is a diabetic and the family fears for his health.

The son of Rev. Michel Louis told The Associated Press on Saturday that his father was on a church group trip to retrace Jesus' steps through the Holy Land when he was abducted. Along with him, a 39-year-old Boston woman in the group and a tour guide were kidnapped Friday when an Egyptian Bedouin stopped their bus on a road linking Cairo to Mount Sinai.

Louis' son, Rev. Jean Louis, said the family is concerned about all three and does not want to discuss communications with the U.S. government so as not to jeopardize their chances for release.
