Yemen's legitimate government said on Friday its forces had intercepted armed drones launched on a southern oil terminal in Hadhramaut province by the Iran-backed Houthi militias as an oil tanker was preparing to dock.
A Yemeni government official said Houthi drones attacked al-Dhabba oil terminal, located in the southern town of al-Shihr, as Nissos oil tanker was preparing to enter the terminal.
Nissos was scheduled to load 2 million barrels of crude from the terminal, the official said, adding that there was no damage to the port and the tanker. The office of Hadhramout's governor Mabkhout bin Madi confirmed the attack to Reuters.
There was no immediate reaction from Houthi officials but a member of the group, Nassruddine Amer, said on Twitter: "Yemen's resources are for the Yemeni people, oil revenues should cover the salaries."
The incident is the first major escalation since the Houthis and government failed to renew a UN-brokered truce earlier this month, amid differences over payment of salaries for civil servants in Houthi-controlled areas.
The United Kingdom Maritime Trade Operations (UKMTO) said it was aware of reports of an incident in the vicinity of al-Shihr and that vessel and crew are safe.
Nissos KEA oil tanker was moving "within zone" on Friday outside al-Dhabba in the Gulf of Aden, Refinitiv data showed.
United Nations special envoy Hans Grundberg said he would continue to push for an extended and expanded deal between the warring parties, both under intense international pressure to come to an agreement.
The truce has largely succeeded in stopping the violence across Yemen as well as allowing some fuel ships into Hodeidah port and some commercial flights from Sanaa, both held by the Houthis.
