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.
Most of the dead were Egyptians, who had been enjoying a Spring holiday in Dahab when the attacks occurred. A German boy was among three foreigners killed.
Some officials were quoted as saying the attacks were the work of suicide bombers, but others said it was too early to say. There has been no immediate claim of responsibility.
The attacks received swift international condemnation.
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.
'Like war'
The three explosions happened in quick succession at about 1900 (1700GMT) in what is a small, low-key resort popular with Western backpackers, budget Israeli tourists and scuba-divers.
Several restaurants, shops and a supermarket were destroyed in the main tourist street close to the seafront during one of the busiest times of the day.

A German doctor, who was holidaying in the town at the time, said a 10-year-old boy died in his arms as he went to the aid of the wounded.
"It was like war," Michael Hartlich told the AFP news agency, still shocked and upset several hours after the blasts. "I'd never seen anything like it before, a child, a baby, blood everywhere, the smell of burnt skin, of burnt hair."
The BBC's Mark Perrow in Dahab saw people sitting dazed near to where the explosions took place as police set up cordons.
The roads in and out of Dahab were being controlled by checkpoints and a virtual curfew existed overnight in the town, our correspondent says.
The emergency services were quickly on the scene, and many volunteers rushed to the town's small hospital to give blood.
The worst of the injured were driven 80 kilometres (50 miles) for treatment at Sharm el-Sheikh or flown on to the capital, Cairo.
Among the 62 wounded there were three Danes, three Britons, two Italians, two Germans, two French people, a South Korean, a Lebanese, a Palestinian, an American, an Israeli and an Australian.
Militant group
Dahab, which means gold in Arabic, lies on the coast of the Gulf of Aqaba, about 100 kilometres (65 miles) south of the border with Israel.
In July 2005, more than 60 people died in a bomb attack in the tourist area of the resort town of Sharm al-Sheikh, further south along the coast.
The BBC's Heba Saleh says the Egyptian authorities have uncovered a militant group active in the Sinai, but they have said very little about it.
The group is also thought to have been responsible for bombings in the resort of Taba in October 2004, when 34 people were killed.
