A fire engulfed four yachts at the Zea (Pasalimani) yacht port in Piraeus near the Greek capital Athens last night, Sky TV reported. Three of them sank, BTA reported.
The fire started at around 3:50 a.m. on a vessel moored at the marina, and then spread to three more of the yachts.
The causes of the fire have not yet been established.
Fire trucks from land and a fire-fighting ship are at the scene. A coast guard ship and a tugboat have also been dispatched.
