Yemen’s Houthi rebels claimed responsibility for drone attacks on 14 September, on a huge Saudi Arabian State-owned Armco petroleum processing facility, which threatens to disrupt global oil supplies.
Both the European Union and the United Nations called for maximum restraint:
“It is important to clearly establish the facts and determine responsibility for this deplorable attack”, the EU stated.
Iran denied responsibility on 15 September, and increased tensions by pointing out that US facilities were within range of Iranian missiles.
The UN chief, António Guterres, condemned the attacks and called upon all parties to exercise maximum restraint, prevent any escalation amid heightened tensions, and to comply at all times with International Humanitarian Law.
Tensions rose in June between Iran, the US, Saudi Arabia and nations involved in the global oil trade, over the key oil shipping lanes around the Strait of Hormuz and the Gulf of Oman, involving tankers damaged at sea, leading to the downing of both Iranian and US drones, while other tankers were seized.
