At least 23 people - including three foreigners - have been killed and 62 wounded in three blasts in the Egyptian resort town of Dahab, officials say.
The explosions occurred in a bustling area popular with tourists during the early evening when many people would have been out in cafes and restaurants.
Eyewitnesses spoke of seeing debris and body parts in the streets.
Southern Sinai peninsula resorts have been hit before. About 60 people were killed in Sharm el-Sheikh last July.
The attack on Dahab, a low-key resort popular with Western backpackers, budget Israeli tourists and divers, was swiftly condemned.
Egyptian President Hosni Mubarak called the explosions a "wicked terrorist act", and US President George W Bush described it as "heinous".
The Hamas-led Palestinian government said it "strongly condemns this criminal act which flouts our religion, shakes Palestinian national security and works against Arab interests".
Israel’s ambassador in Cairo urged Israelis in Sinai to leave immediately, and a stream of Israeli cars were reportedly heading to the Israeli border at Taba by late evening.
Israel has offered to send emergency teams to the scene, the defence ministry said.
