U.S. President Barack Obama and new Saudi Arabia King Salman are expected to discuss shared concerns about the turmoil in Yemen and the fight against Islamic State militants during their first formal meeting in Riyadh on Tuesday, the White House said.

The turmoil hitting Saudi Arabia's neighbor Yemen will pose the first big test for King Salman, and provide a glimpse as to whether his approach to hotspots in a fragmenting region will differ from that of his late brother.

U.S. President Barack Obama will visit Saudi Arabia on Tuesday to meet its new King Salman after the death of his predecessor Abdullah on Friday, testimony to Riyadh's important role in energy markets and the fight against Islamist militancy.
