President Joe Biden held a long-delayed first phone call on Feb. 25 with Saudi King Salman ahead of an imminent U.S. intelligence report expected to link the Arab kingdom's powerful crown prince to the killing of dissident journalist Jamal Khashoggi.

Biden kept the king waiting in his long list of calls to U.S. allies after being sworn in five weeks ago.

A suicide bomb attack inside a mosque in a local security forces headquarters in Abha city in south-west Saudi Arabia killed 13 people and wounded nine on Aug. 6, the Saudi state news agency reported, citing an interior ministry spokesman.

State television had earlier reported a death toll of 17. 

Saudi Arabia's King Abdullah said terrorism would soon spread to Europe and the United States unless it is quickly dealt with in the Middle East, the Saudi state news agency reported late on Aug. 29. 

The king made the statement during a reception for foreign ambassadors held in Jeddah.
