EL-ARISH, Egypt — Egyptian security officials say they will not give in to demands of a Bedouin man who took two Americans and their local translator hostage in the Sinai Peninsula.

Rev. Michel Louis, an American woman and their Egyptian guide were taken off a bus on a road between Cairo and Mount Sinai on Friday while on a church trip.

The hostage-taker, Jirmy Abu-Masuh, has said he will not free the two Boston natives until his uncle is released from jail.

Egyptian officials say they will not release the uncle until he completes a 15-day prison sentence for possession of drugs. Abu-Masuh says his uncle was jailed for refusing to pay the police a bribe.

The officials spoke Monday on condition of anonymity to discuss the negotiations.
