King Salman (R) and Donald Trump spoke in a call this week.

:: US President Donald Trump on Monday said that “interesting things are happening” on Middle East peace, following a phone call he held with the king of Saudi Arabia.

“Spoke yesterday with the King of Saudi Arabia about peace in the Middle-East. Interesting things are happening!” the president posted on Twitter.

It was not immediately clear whether Trump was referring to Saudi Arabia’s ongoing rift with Qatar, but during the phone call on Monday the president expressed his “concerns” over the crisis.

In calls to leaders of Saudi Arabia, Abu Dhabi and Qatar, Trump had “reiterated the importance of stopping terrorist financing and discrediting extremist ideology. The president also underscored that unity in the region is critical to accomplishing the Riyadh Summit’s goals of defeating terrorism and promoting regional stability,” the White House said, according to Reuters news agency.

“President Trump, nevertheless, believes that the overriding objective of his initiative is the cessation of funding for terrorism,” it said.

Saudi Arabia, Bahrain, UAE and Egypt broke off the ties last month over allegations of Qatar’s links to terrorism.
