A timeline of developments since the surprise announcement by Prime Minister Saad Hariri from Saudi Arabia that he was resigning.

Lebanon's divided politicians rarely agree on anything, but they have fleetingly united in calling for Prime Minister Saad Hariri to return home, even if their motivations vary vastly.

Hariri announced his resignation on November 4, in a shock statement delivered from Saudi Arabia on the kingdom's Al-Arabiya television station.

Lawyers and supporters of the chief suspect in a deadly attack on a Paris synagogue in 1980 expressed disappointment at his being denied release for an eighth time on Tuesday.

French President Emmanuel Macron, in a fresh statement via a spokesman Wednesday, stressed that Prime Minister Saad Hariri should be able to return to Lebanon to confirm, or not, his resignation.

French Foreign Minister Jean-Yves Le Drian will meanwhile meet with Hariri on Thursday during a visit to Saudi Arabia, an aide said.

President Michel Aoun on Wednesday accused Saudi Arabia of having "detained" Prime Minister Saad Hariri, who announced his resignation in a statement from the kingdom earlier this month.

"Nothing justifies the failure of Prime Minister Saad Hariri to return for 12 days, therefore we consider him to be held and detained, contrary to the Vienna Convention," Aoun said in a tweet on the official Lebanese presidency account.

Al-Mustaqbal Movement strongly replied to Syrian President Bashar Assad's accusations against Prime Minister Saad Hariri, urging him to “stop sticking his nose in Lebanon's affairs.”

Prime Minister Saad Hariri, who submitted his resignation on November 4 from Saudi Arabia, will reportedly return to Lebanon within two days, al-Akhbar daily reported on Wednesday.

The Lebanese army on Tuesday arrested fugitive Islamist cleric Mustafa al-Hujeiri, aka Abou Taqiyeh, in the northeastern border town of Arsal, the Army Command-Orientation Directorate said in a statement.

The statement added that the arrest was made early at dawn and that interrogations have kicked off with the related judiciary.

From global warming to Iran's nuclear deal, France's Emmanuel Macron has already intervened in a series of diplomatic quagmires -- and now finds himself pursuing an active role in Lebanon's crisis.

He and his ministers have held a flurry of talks with players shaping the turmoil, with Macron jetting to Saudi Arabia last week for surprise talks with the crown prince.

Al-Mustaqbal parliamentary bloc stressed Tuesday that its “priority” is the return of Prime Minister Saad Hariri to Lebanon, as it urged an end to “interference in the internal affairs of Arab countries.”

“The priority in the bloc's discussions and meetings is the return of PM Saad Hariri to Lebanon,” said the bloc in a statement issued after its weekly meeting.
