Hariri posted a selfie with Mohammed bin Salman and the kingdom's ambassador to the United States following their meeting in Riyadh late yesterday at the end of a three-day visit.
The three appeared in informal clothes and flashed wide smiles, apparently signalling relations have been normalised following last year bizarre sequence of events around Hariri's resignation.
Hariri's resignation, announced while he was in Riyadh, was widely seen as orchestrated by his Saudi backers who complain that the Lebanese government is controlled by the powerful Iran-backed Hezbollah group.
