Saudi king meets Obama amid concerns over Iran deal

King Salman of Saudi Arabia has met President Barack Obama in Washington, on his first trip to the United States since assuming the throne in January.

The meeting came amid a period of strained bilateral relations.

The king reiterated the concern of Gulf states over the recent deal on Iran's nuclear programme.

They fear that lifting sanctions could allow Iran to extend its support for militant groups and actions across the region they consider destabilising.
