Egyptian authorities say 10 people have been detained in connection with bombing attacks that killed 18 people late Monday in the Sinai resort city of Dahab.
Security sources identified three of the suspects as Egyptian computer engineers who arrived in Dahab Sunday and tried to leave after the blast Monday in a car with fake license plates.
The Egyptian Interior Ministry said six foreigners and 12 Egyptians were killed, revising an earlier death toll of 23. A spokesman said 62 people were wounded in the almost simultaneous explosions.
The spokesman said police are working to determine whether the blasts were triggered by timers or by remote control. There has been no claim of responsibility.
President Bush telephoned Egyptian President Hosni Mubarak today, offering condolences and pledging to stand with Egypt in the fight against terrorism.
U.N. Secretary-General Kofi Annan also denounced the bombings and extended condolences to the victims. Israel offered to send emergency teams to help.
Nearly 100 people have been killed in terrorist attacks on Sinai resorts since October 2004. Last July, similar bomb explosions at Sharm el-Sheikh, on the Red Sea, killed at least 64 people.
Monday evening's attack came during Coptic Christian celebrations of Easter, and one day before Egypt's annual observance of Sinai Liberation Day, marking Israel's withdrawal from the Sinai Peninsula in 1982.
