DHAHRAN, Saudi Arabia (AP) — Saudi Arabia used its perch as host of an annual gathering of Arab leaders on Sunday to push for a unified stance against rival Iran as the regional powerhouses vie for the upper hand in wars in Syria and Yemen.

Saudi King Salman told leaders from across the 22-member Arab League that Iran was to blame for instability and meddling in the region. He said Yemeni rebel Houthis, backed by Iran, had fired 116 missiles at the kingdom since Saudi Arabia went to war in Yemen three years ago to try and roll back Houthi gains there.
