CAIRO, Egypt (AP) _ Two energy experts from the United States and two Egyptians were killed in a collision between their van and a bus near the Red Sea coast, the U.S. Embassy and Egypt's Middle East News Agency said Tuesday.

Two other American energy experts were injured in the crash Monday night, an embassy spokeswoman said on condition of anonymity.

The spokeswoman said the crash occurred as the four Americans and an Egyptian engineer were en route to the Red Sea Port of Hurghada, 250 miles southeast of Cairo, in a chauffeur-driven van.

She said she had no details of the collision and could not provide names of the victims until families were notified.

The embassy spokeswoman said the dead Americans were employees of Burns and Roe, a consulting firm based in Ordell, N.J. She said the injured Americans work for another consulting firm, R. Lynette and Associates, of Redmond, Wash.

She said the firms were under contract to the U.S. Agency for International Development and were working on an energy project for Egypt's Ministry of Electricity in the Hurghada area.

The Egyptian news agency said Mohammed Metwalli Sayed, an Egyptian engineer accompanying the Americans, and Sayed Mahmoud, the van's driver, died in the collision.

The bodies of the dead Americans were flown to Cairo on Tuesday, the news agency said. The embassy spokeswoman said they will be sent home for burial.
