Local reports cited by Reuters and CNN say a ferry traveling from Kyrenia toward Turkey overturned with roughly 270 people aboard.

A search-and-rescue operation was underway Sunday after a passenger ferry capsized off northern Cyprus while traveling from Kyrenia, also known as Girne, toward Taşucu on Turkey’s southern coast.

Reuters, citing Turkish Cypriot media, reported that around 270 people were aboard. Kyrenia Mayor Murat Şenkul told CNN Türk that 159 of the vessel’s 258 passengers had been reached, according to Reuters.

Local reporting said the vessel began taking on water several miles from shore before overturning. Rescue crews, ambulances and vessels in the area were deployed, while authorities worked to transfer passengers from the scene.

The total number of people aboard has varied across early reports, and officials had not released a confirmed casualty toll or a cause for the capsizing. The incident remained an active, developing emergency.
