The almost simultaneous bombings, the third attack against Sinai peninsula resorts in 18 months, drew condemnation from world leaders and President Hosni Mubarak vowed to punish the perpetrators of these "heinous acts of terrorism."

The interior ministry said 20 Egyptians and three foreigners, including a German baby, were among the dead. Security officials had earlier said a Swiss national and a Russian were killed.

The bombs hit the Ghazala supermarket and the Nelson and Aladdin restaurants in the busiest part of Dahab, a popular destination for divers and backpackers whose name means gold in Arabic.

"Around 7 pm (1600 GMT), we heard three explosions close to the seafront alongside a supermarket in the centre of Dahab," French tourist Frederic Mingeon told AFP.

"There was a plume of smoke and people started running and screaming."

French, American, British, Italian, Arab and Israeli nationals were among the injured, according to security sources.

State television said the blasts appeared to have been the result of remote-controlled bombs, not suicide bombers.

Footage of the scene aired by Egyptian state television showed lumps of flesh lying in pools of blood in front of the mangled remains of shopfronts in Dahab, which lies on the southeast coast of the peninsula about 530 kilometres (330 miles) by road from Cairo.

No-one immediately claimed credit for the attacks, which came one day after a new audiotape of Al-Qaeda leader Osama bin Laden surfaced accusing the "crusaders" of the West of waging war against Islam, referring to the conflict in Darfur and the isolation of the Hamas-led Palestinian government.

Dahab, which is popular with Western backpackers and budget Israeli tourists, was also packed with Egyptians enjoying a public holiday.

The bombers struck on Sham el-Nessim, a traditional holiday which marks the beginning of spring, and a day before Sinai Liberation Day which celebrates Israel's withdrawal from the peninsula in 1982.

"The street was littered with debris and I could see pools of blood," added Belgian tourist Quentin d'Aspremont.

Medical staff at Dahab hospital were in the process of identifying more of the victims before sending them to the nearest morgue in Sharm el-Sheikh at the tip of the Sinai.

The resorts of Egypt's south Sinai peninsula have been repeatedly hit by Islamist militants.

Multiple bombings in Sharm el-Sheikh killed about 70 people in July 2005, the deadliest to have hit Egypt since a major wave of Islamist attacks in the mid-1990s, many targeting foreigners.

At least 34 people were killed in several simultaneous attacks in and around the resort of Taba further up the Red Sea coast near the Israeli border in October 2004.

Four groups claimed the Sharm el-Sheikh bombings, including Al-Tawhid wal Jihad, an Islamist movement which said the attacks were revenge for the invasions of Iraq and Afghanistan and out of allegiance to bin Laden.

US President George W. Bush branded the Dahab bombings a "heinous act."

"I strongly condemn the killings that took place, the innocent lives lost," Bush said. "I assure the enemy ... we will bring them to justice for the sake of justice and humanity."

British Foreign Secretary Jack Straw described the attacks as "appalling" and added: "Once again terrorists have demonstrated their callous disregard for human life."

Israeli prime minister-designate Ehud Olmert also sent his condolences to Mubarak and his office said the two leaders discussed "the need for cooperation between the two countries in the fight against international terrorism."

The streets of Dahab were immediately sealed off by police and Egyptian security sources said the border with Israel, which lies only around 90 miles north of Dahab, was closed to prevent the attackers from fleeing.

A state of alert was declared at the main hospital in the Israeli border town of Eilat to handle any casualties sent for treatment there and to free up doctors for dispatch to the scene.

In April last year, two French tourists and an American were also killed and some 20 people wounded in a bomb attack in the Al-Azhar area of the Egyptian capital.

Seven people were wounded in an attack later the same month in Cairo and two women assailants were killed in a failed attack on a tourist bus.
