on Monday, a Saudi general and two border guards died in a shootout along the Iraqi–Saudi Arabian border with fighters thought to be members of the Islamic State of Iraq and al-Sham (ISIS). The attack—the first against Saudi Arabia since it joined the U.S.-led coalition against ISIS—came amid uncertainty both at home and abroad, over questions surrounding the health of 90-year old King Abdullah, who is in the hospital battling pneumonia, and over the global price of oil.
