Authorities in Egypt say a luxury yacht that set off with 44 people from the Red Sea port of Ghalib for a week-long diving trip sank, with 32 rescued and 8 still missing.

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.

Four bodies were retrieved one day after Monday’s shipwreck, according to local authorities. Search teams rescued 33 people and seven people remained missing on Tuesday.
