An anti-ship cruise missile fired by Yemen's Houthi rebels struck a Norwegian-flagged tanker in the Red Sea near a key maritime chokepoint known as the Bab el-Mandeb Strait, where nearly 10% of all crude traded at sea passes through.
Reuters quoted Houthi military spokesperson Yehia Sarea, who said the tanker - named "Strinda" - was targeted because it was headed to an Israeli terminal, and the crew ignored all warnings.
However, Strinda's owner, Norway's Mowinckel Chemical Tankers, said the vessel was bound for the Suez Canal and then on to Italy with a cargo containing vegetable oil and biofuels.
A US official told Reuters that the attack occurred about 60 nautical miles north of Bab al-Mandab Strait, connecting the Red Sea and the Gulf of Aden around 2100 GMT. After the attack, another official said the tanker could move under its own power.
