An American Roman Catholic priest being held hostage by Lebanese terrorists said he does not want to be freed by military force, according to a letter released by his family. Relatives of Father Lawrence Jenco, who was kidnaped in West Beirut on Jan. 8, said in Joliet, Ill., that Jenco wrote that he is being held hostage for men being held in Kuwait--an apparent reference to Arabs jailed there for terrorist bombings against French and American targets. He added that "military intervention on my behalf will not be good for me." The priest is believed to be held by Shia Muslim terrorists loyal to Iran. Four other Americans are also being held hostage in Lebanon.
