Four bodies were recovered on Tuesday from a tourist boat which capsized off Egypt’s Red Sea coast, and rescue teams were still searching for nine missing people, the Red Sea Governorate said in a statement.

Nine people remain unaccounted for after a tourist boat sank on Monday after leaving the Egyptian port of Marsa Alam.

Authorities in Egypt say a luxury yacht that set off with 45 people from the Red Sea port of Ghalib for a week-long diving trip sank, with 28 rescued and 16 still missing.
