The owner of a tanker reported attacked today in the Mediterranean Sea has said there was no such incident.
Petronav Ship Management said its tanker, Olvia, was not targeted as claimed by Yemen's Houthi militants.
An attack in the Mediterranean would be a big step outside the Houthi's region of operations, which is limited to the area in and around the Bab el-Mandeb strait at the southern end of the Red Sea.
The Houthis claimed two other attacks today in the Red Sea, on crude tanker Chios Lion and oil product tanker Bentley I.
