There have been three explosions in the Egyptian resort town of Dahab, on the east side of the Sinai peninsula.
At least 22 people were killed and up to 150 were injured.
Egyptian television reports say the blasts in a market and a busy restaurant area were apparently carried out by remote control rather than suicide bombers.
An official with the local ambulance service said many of the dead appeared to be foreigners.
Last July, at least 60 people were killed and more than 200 were wounded in another triple explosion in Egypt's tourist area of Sharm el-Sheikh.
The attack on Dahab, a low-key resort popular with Western backpackers, budget Israeli tourists and divers, was swiftly condemned.
The Minister for Foreign Affairs, Dermot Ahern, TD, expressed his horror at reports of the bomb attacks, saying they were ‘appalling outrages’.
Egyptian President Hosni Mubarak called the explosions a ‘wicked terrorist act’, and US President George W Bush described it as a ‘heinous act’.
