Lebanon's president said Thursday he was waiting for Saad al-Hariri to return from France to decide on the next steps, after Beirut accused Saudi Arabia of detaining the premier following his shock resignation.

"I am awaiting the return of Prime Minister Hariri from Paris for us to decide the next step with regards to the government," the presidency's Twitter account quoted Michel Aoun as saying.

Hariri has not returned to Lebanon since he announced his resignation while in Saudi Arabia on November 4. French Foreign Minister Jean-Yves Le Drian said Thursday during a visit to the kingdom that Hariri would travel to France.
