Yemen's Iran-aligned Houthi movement said on Wednesday it targeted facilities belonging to Saudi Aramco in Jizan on the Red Sea in response to "escalating airstrikes" but there was no immediate confirmation from Saudi Arabian authorities.
State oil giant Aramco declined to comment on the report.
Houthi military spokesman Yahya Saria did not give a timeframe for the assault. He said in a statement that the group that has been battling a Saudi-led military coalition for nearly five years had also targeted non-energy Saudi facilities near the border with Yemen.
