Egyptian rescuers found four bodies and five survivors during a Red Sea search operation after a tourist boat carrying 44 people sank on Monday.
A total of 33 people have been rescued so far but seven are still missing.
The victims’ identities have not yet been disclosed by authorities.
The four-deck modern vessel had been carrying 31 passengers and 13 crew when it is understood to have been hit by a large wave near Marsa Alam, causing it to capsize.
The vessel sank within five to seven minutes, according to Red Sea governor Maj-Gen Amr Hanafi. He said some people had been unable to escape from their cabins.
A total of 28 people were rescued by military personnel and a passing tourist boat in the hours after the vessel capsized.
The governor had earlier said other survivors were found in the Wadi el-Gemal area, south of Marsa Alam.
