Saudi oil chief says energy security imperiled by attacks

Saudi Arabia’s oil chief said markets are going through a “jittery period” and reiterated Tuesday that the kingdom’s ability to ensure energy security is no longer guaranteed. Energy Minister Prince Abdulaziz bin Salman said cross-border attacks have put to question “our ability to supply the world with the necessary energy requirements.” The attacks have been carried out by Yemen’s rebel Houthis, who are supported by Iran.
