US President Donald Trump is expected to underline the need to confront extremism in Islam when he makes a speech in Saudi Arabia latertoday.
His address, to a summit of regional leaders, will come on the second day of his first presidential trip abroad.
It is expected he will attempt to strike a collaborative tone in attempts to bolster support for the US fight against Islamic State militants.
Yesterday, the US signed trade deals of 350 billion dollars with Saudi Arabia.
This included the largest arms deal ever made in US history, which Secretary of State Rex Tillerson said was aimed at countering the "malign" influence of Iran, Saudi Arabia's regional rival.
But the president's visit has been overshadowed by his political difficulties at home, namely the fallout over his sacking of FBI chief James Comey.
