Egyptian security forces launched a search late Friday for two Sudanese suspected of planning attacks against government installations and tourist resorts in the Sinai, an Egyptian security official said. The suspects are believed to be driving in an explosives-laden Toyota pickup truck, said the official. The search began after urgent instructions from the Egyptian interior ministry to police offices across the Sinai Peninsula. The official added that the police, including reinforcements sent to the area, have set up ambushes and were searching through main cities in the Sinai and recruited local Beduin tribesmen to help search for the suspects. Beduin are traditionally experts at navigating the desert and finding back ways to avoid checkpoints.
