At least six people died when a ferry capsized off Northern Cyprus on Sunday, the head of the local government said, in a preliminary toll to Turkish media.

Unal Ustel, prime minister of the self-proclaimed Turkish Republic of Northern Cyprus (TRNC), said the vessel had been carrying a total of 267 people when it rolled over shortly after leaving port, according to Turkish state news agency Anadolu.

Ustel added that 172 people had so far been rescued and that operations were continuing to evacuate the remaining passengers and crew, Anadolu said.

Turkiye’s ambassador to Nicosia, Ali Murat Basceri, confirmed there were deaths, without giving a number. He told Turkish state television network TRT that “the large majority of the 259 passengers have been rescued”.

The cause of the capsize was not immediately known.
