Prime Minister Saad Hariri said he will return to Lebanon for Wednesday's Independence Day celebrations and explain his situation after his shock resignation announcement in Saudi Arabia sparked political turmoil.
Speaking after talks in Paris on Saturday with French President Emmanuel Macron, who is seeking to broker a way out of the crisis, Hariri said he would "make known my position" once back in Beirut.
"As you know I have resigned, and we will discuss that in Lebanon," he told reporters, saying he needed to meet with President Michel Aoun before taking further steps.
The news follows two weeks of deep uncertainty after Hariri's surprise announcement to step down on November 4.
His failure to return to Lebanon since sparked rumours that he was being held in Riyadh against his will, which both he and Saudi officials denied.
"To say that I am held up in Saudi Arabia and not allowed to leave the country is a lie," he said in a Twitter post just before flying to Paris overnight.
Hariri's wife and eldest son Houssam joined him for lunch with Macron at the Elysee Palace, but their two younger children, who live in Saudi Arabia, have remained there "for their school exams", a source close to the premier said.
After the meeting, Macron's office said the president will "continue to take all necessary initiatives for Lebanon's stability."
"We are helping to ease tensions in the region," the Elysee Palace added.
Hariri's mysterious decision to step down -- which president Aoun has refused to accept while Hariri remains abroad -- has raised fears over Lebanon's fragile democracy.
Hariri's camp has sought to allay the concerns, with a source saying the premier had a "fruitful and constructive" meeting with the powerful Saudi crown prince.
Hariri -- whose father, ex-prime minister Rafiq Hariri, was killed in a 2005 car bombing blamed on Hezbollah -- took over last year as head of a shaky national unity government which includes the powerful Shiite movement.
A dual Saudi citizen who has previously enjoyed Riyadh's backing, he resigned saying he feared for his life.
He accused Saudi Arabia's arch-rival Iran and its powerful Lebanese ally Hezbollah of destabilising his country.
Saudi Arabia's Foreign Minister Adel al-Jubeir meanwhile insisted from Madrid on Friday that "unless Hezbollah disarms and becomes a political party, Lebanon will be held hostage by Hezbollah and, by extension, Iran".
Hariri's resignation was widely seen as an escalation of the battle for influence between Sunni Saudi Arabia and Shiite Iran, which back opposing sides in the conflicts in Syria and Yemen.
His attempt to step down also coincides with a purge of more than 200 Saudi princes, ministers and businessmen.
Riyadh on Saturday recalled its ambassador to Berlin in protest at comments by Germany's Foreign Minister Sigmar Gabriel which were interpreted as a suggestion that Hariri acted under Saudi orders.
Without mentioning Saudi Arabia directly, Gabriel had said Thursday that he shared concerns about the threat of instability and bloodshed in Lebanon and warned against "adventurism".
"Lebanon has earned the right to decide on its fate by itself and not become a pinball of Syria or Saudi Arabia or other national interests," he had said earlier in the week.
Germany's foreign ministry had yet to comment on the row, but in a statement it welcomed Hariri's "imminent return to Lebanon".
France's intervention was the latest in a string of European efforts to defuse tensions over Lebanon, where divisions between Hariri's Sunni bloc and Shiite Hezbollah have long been a focal point in a broader struggle between Riyadh and Tehran.
Paris, which held mandate power over Lebanon for the first half of the 20th century, plans to bring together international support for Lebanon, depending on how the situation develops.
The French president has also telephoned his counterparts in the US and Egypt, Donald Trump and Abdel Fattah al-Sisi, as well as the Saudi Crown Prince Mohammed Bin Salman and UN Secretary-General Antonio Guterres to discuss "the situation in the Middle East".
He and Trump "agreed on the need to work with allies to counter Hizballah's and Iran's destabilizing activities in the region", according to a White House statement Saturday.
However, Macron told reporters Friday that France wanted "dialogue" with Iran and aimed to "build peace... not to choose one side over another".
Ahead of Hariri's departure, Aoun -- an ally of Hezbollah -- welcomed the trip to Paris, expressing hope that it was the "start of a solution".
"If Mr Hariri speaks from France, I would consider that he speaks freely," Aoun said.
"But his resignation must be presented in Lebanon, and he will have to remain there until the formation of the new government."
