Yemen's Houthis renewed threats against Saudi oil facilities, airports and aviation on 8 October as fighting escalates between the group and forces aligned with Yemen's Saudi-backed internationally recognised government.
"The armed forces warn all employees, experts and engineers working at all Saudi oil facilities not to be present in locations that represent targets for our forces so as not to endanger their lives," Houthi military spokesman Yahya Saree said.
Saree said the warning covered facilities that had not previously been attacked, as well as those already targeted by the group.
The Houthis have repeatedly targeted Saudi energy infrastructure in recent weeks. They most recently claimed attacks on state-controlled Saudi Aramco facilities in Riyadh and Khurais on 4 October, after reporting a separate strike on an Aramco site in Riyadh a day earlier. The group said the attacks caused fires.
Two sources separately confirmed an incident at the 126,000 b/d Riyadh refinery on 3 October, with one saying a storage tank was hit. There was no independent confirmation of the subsequent attacks.
The group has also previously targeted the 400,000 b/d Jizan refinery on Saudi Arabia's Red Sea coast and facilities further north in Yanbu.
Saree also renewed an earlier threat against Saudi civilian airports and aircraft using the country's airspace.
Several Saudi airports have come under Houthi missile and drone attack in recent weeks. Saudi aviation regulator GACA said late on 7 October that attacks on Riyadh's King Khalid International airport and Abha International airport this week had killed three people and injured 36.
The Houthis claimed another missile attack on King Khalid airport early on 8 October, which they said "struck its target with precision and caused a disruption of airport operations".
Navigation service Flightradar24 listed 322 flights scheduled to arrive at or depart King Khalid International airport as cancelled and 185 as delayed as of 17:00 local time today.
