Saudi Authorities Say Riyadh Airport Attack Killed 12

Saudi authorities say the latest attack on the international airport in the capital, Riyadh, killed 12 people and injured more than 300. NPR reports that the attack is the latest of several in the past week on King Khalid International Airport, and that it is expected to increase Saudi pressure on allies, including the United States, to provide military support for the kingdom. The casualty figures come from the Saudi statement. The diplomatic consequence is reported as an expectation — that Riyadh will press harder — rather than as any commitment allies have made.
