Houthi rebels in Yemen attacked Saudi Arabia this week from Iraqi territory, in coordination with pro-Iranian militias operating in the country, according to two regional sources who spoke to Reuters, citing assessments from Saudi Arabia and regional partners. The attacks included strikes on oil facilities in eastern Saudi Arabia, which constitute the kingdom's main crude oil hub. In response to those attacks, Saudi Arabia, together with the United States, bombed sites in Iraq and, according to reports, killed about 20 Revolutionary Guard advisers.
