Riyadh: A fire broke out at an oil terminal in southern Saudi Arabia after it was hit by a projectile, the energy ministry said Friday, the sixth anniversary of a Riyadh-led military intervention in Yemen.

“A projectile attack on a petroleum products distribution terminal in Jizan... resulted in a fire in one of the terminal’s tanks,” the ministry said in a statement published by the official Saudi Press Agency, adding that no casualties were reported.

It did not say who was behind the strike on Thursday, but it comes as Yemen’s Houthi rebels increasingly mount attacks on the kingdom’s energy installations.

The attack comes after Saudi Arabia on Monday offered the Houthis a “comprehensive” UN-supervised ceasefire, as part of a series of fresh proposals aimed at ending the catastrophic six-year conflict.

Riyadh led a military coalition into Yemen in March 2015 to prop up the internationally recognised government.

The coalition says it enforced a naval and air blockade to prevent the smuggling of weapons to the rebels from Iran.
