Lebanon's Saad Hariri, who resigned as prime minister at the weekend, is "free to move around", French Foreign Minister Jean-Yves Le Drian said Friday amid rumours he was being held against his will in Saudi Arabia.

"He went to Abu Dhabi the day before the President (Emmanuel) Macron's visit (on Wednesday) so we think he's free to move around," Le Drian told Europe 1 radio.
