Lebanon was left reeling Sunday without the slightest prospect of ending multiple crises, after its premier-designate stepped down following the failure of talks to form a government, despite international pressure.

Mustafa Adib's resignation on Saturday ended efforts to hammer out a reformist government in the wake of a colossal August 4 explosion in Beirut that killed 190 people, injured thousands and ravaged large parts of the capital.

The binding parliamentary consultations to name a new premier following the resignation of PM-designate Mustafa Adib will not be imminent, media reports said.

“The call for parliamentary consultations to pick a prime minister will not be quick,” Presidency sources told Asharq al-Awsat newspaper in remarks published Sunday.

Free Patriotic Movement chief Jebran Bassil has tested positive for coronavirus, his office said Sunday.

The statement from his office said Bassil will isolate until he recovers, adding that the infection level is still "low and acceptable."

Israel will hold rare talks with Lebanon next month in an effort to resolve a longstanding maritime border dispute, an Israeli official said.

The official said Energy Minister Yuval Steinitz will lead the Israeli delegation in talks mediated by the United States. Representatives from the three countries are likely to speak by video conference because of the coronavirus pandemic, the official said.

Gunmen opened fire on an army post in the northern area of Araman at dawn Sunday, triggering a shootout in which two soldiers and one gunman were killed, the army said.

Another gunman fled to an unknown destination, according to an army statement.

From the Beirut port blast to premier-designate Mustapha Adib stepping down on Saturday after less than a month of trying to form a new cabinet, here are developments in crisis-hit Lebanon:

Mustapha Adib, a little-known diplomat tasked with forming a new crisis government to save Lebanon from the brink, resigned Saturday after less than a month as premier designate.

UN Special Coordinator for Lebanon Jan Kubis on Saturday criticized Lebanon’s politicians for thwarting the French initiative to assist Lebanon, shortly after the resignation of PM-designate Mustafa Adib over a Cabinet impasse.

“Such a degree of irresponsibility, when the fate of Lebanon and its people is at stake! Politicians, have you really scuppered this unique chance created by France? …” said Kubis in a tweet.

President Michel Aoun accepted the resignation of PM-designate Mustafa Adib and was set to "take the appropriate measures according to the requirements of the constitution", the president's office said Saturday.

Lebanese Forces leader Samir Geagea issued a statement on Saturday in which he congratulated PM-designate Mustafa Adib for stepping down “because he could not put his convictions into action.”

“My warm congratulations to PM Adib, even if we had not named him, because he is the first Lebanese official to resign when he saw an inability to translate his convictions,” said Geagea, shortly after Adib’s resignation from Baabda because of a Cabinet impasse.
