Three Egyptians have been sentenced to death over a series of bomb attacks in Sinai resorts that killed 34 people in October 2004.
The Taba Hilton hotel was badly damaged in the attacks
The three men were found guilty of various terror-related charges at a state security court in Ismailiya.
More than 100 people were injured in three simultaneous bombings targeting a hotel in Taba and a backpacker camp a few miles along the coast on 7 October.
Resorts in Sinai have been hit by a series of bombings in recent years.
The three men were named as Younes Mohammed Mahmoud, Osama al-Nakhlawi and Mohammed Jaez Sabbah.
They were found guilty of terrorism, murder, illegal possession of weapons and belonging to a terror group, the Associated Press reports.
Prosecutors said they belonged to a group called Tawheed and Jihad - a group which is believed to be made up of Sinai Bedouin with militant Islamist views.
A further 10 defendants were also sentenced by the court to between five years and life imprisonment for their part in the attacks.
All pleaded not guilty. Some say they were forced to make confessions under duress.
The October 2004 bombings took place at the Hilton hotel in Taba and the Ras al-Shitan campsite resort near Nuweiba.
Both resorts were packed with Israeli tourists who had travelled there during a Jewish holiday.
Many of the dead were Israelis, but Russians, Egyptians and Italians were also killed.
More than 2,000 people were reported to have been arrested in the weeks following the attacks, which badly damaged part of the Hilton hotel.
Egypt has said little about its investigations of this and other attacks in Sinai, although suspicion has long fallen on Tawheed and Jihad.
The attack on the Taba Hilton and Ras al-Shitan was followed in July 2005 with a triple bombing of the Sharm el-Sheikh resort, which killed 60 people.
More than 20 people were killed when the resort of Dahab was targeted last April.
