US President Barack Obama will meet with Saudi Arabia's King Salman on Sunday, a US official says.
The meeting will be held in Turkey as world leaders are seeking a united response to the Paris attacks, which Daesh (ISIL) terrorists claimed responsibility for.
The assaults took place on Friday in at least six different venues in and around Paris, killing nearly 130 people and injured about 350 others.
Obama and Salman will hold bilateral talks on the sidelines of the two-day G20 summit in the heavily guarded Turkish Mediterranean resort of Antalya.
According to the US official, the two leaders will discuss the fight against Daesh violence on top of other topics.
Riyadh is part of a US-led coalition that launched an air campaign in 2014 targeting purported ISIL positions in Syria and Iraq.
On September 4, Obama and Salman also met in Washington and discussed how to end the ongoing crisis in Syria.
“We share concerns about the crisis in Syria and will have the opportunity to discuss how we can run a political transition process within Syria and how we can finally end the horrific situation there,” Obama said during the meeting.
Syria has been gripped by a foreign-backed militancy since March 2011. The crisis has claimed the lives of more than 250,000 people so far and displaced millions of others.
The US—with help from its regional allies especially Saudi Arabia, Turkey and Qatar—has been training and arming militant units to fight against Daesh terrorists and the Syrian government.
