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.

French Prime Minister Edouard Philippe said Tuesday that Prime Minister Saad Hariri must be able to return to Lebanon from Saudi Arabia to end uncertainty caused by his shock resignation.

"What's at stake is Mr. Hariri being able to return home freely to clarify his situation in line with the Lebanese constitution," Philippe told French parliament, saying his resignation, announced in Saudi Arabia, had caused "a period of uncertainty."

Prime Minister Saad Hariri announced Tuesday that he is “doing very well” and that he will return from Saudi Arabia to Lebanon within days.

“Folks, I'm doing very well, and God willing I will return within days, so let's be patient,” Hariri tweeted in Lebanese dialect, in his first tweet since November 6.

German Chancellor Angela Merkel held phone talks Tuesday with President Michel Aoun, reassuring him that her country is exerting efforts to resolve the crisis sparked by Prime Minister Saad Hariri's resignation, the Lebanese Presidency said.

Merkel told Aoun that she is following up on the developments in Lebanon, lauding “the role that President Aoun is playing to find a solution to this situation,” the Presidency added.

The Saudi Embassy in Beirut has received threats that an unknown group will kidnap 15 Saudi citizens in Lebanon, media reports published Tuesday said.

“The embassy received three phone calls in which unknown individuals calling themselves 'Mulathamoun' (Masked) threatened to abduct fifteen Saudi citizens in Lebanon,” London-based Saudi daily al-Hayat reported.

Prime Minister Saad Hariri snapped back Tuesday at a senior Iranian official over remarks about their recent meeting in Beirut.

“Hariri's latest statements were Saudi diktats,” said Ali Akbar Velayati, chief foreign policy adviser to Iran's supreme leader Ali Khamenei, referring to Hariri's TV interview on Sunday.

Foreign Minister Jebran Bassil has flown to Brussels on the first leg of a European tour that aims to rally support for Lebanon's stability following Prime Minister Saad Hariri's contentious resignation from Saudi Arabia.

“Lebanon is still addressing the problem with Saudi Arabia within the framework of brotherly bilateral ties and the tour is to urge the kingdom to realize that what's happening is unacceptable,” Bassil said after arriving in Brussels.

Hizbullah is at the center of the recent crisis that has gripped Lebanon and rattled a region already rife with conflict.

When Saudi-backed Prime Minister Saad Hariri declared his resignation in a surprise announcement from the Saudi capital, Riyadh, he blamed Hizbullah for imposing itself on the country and doing the bidding of its main backer, Iran, in Lebanon and elsewhere in the region.

Maronite Patriarch Beshara al-Rahi held separate talks Tuesday in in Riyadh with Saudi King Salman, Crown Prince Mohammed bin Salman and Prime Minister Saad Hariri as part of a historic visit to the kingdom.

The visit comes amid tensions between the two countries after Hariri's shock resignation.

Saudi Arabia's dramatic moves to counter Iran in the region appear to have backfired, significantly ratcheting up regional tensions and setting off a spiral of reactions and anger that seem to have caught the kingdom off guard.

Now it's trying to walk back its escalations in Lebanon and Yemen.
