The European Union expressed "disappointment and concern" Monday about the resignation of Lebanon's prime minister-designate over the weekend and urged the country's leaders to do their best to form a Cabinet that meets the demands of the people.

Mustafa Adib's resignation during a political impasse came amid Lebanon's worst economic and financial crisis in decades -- made worse by a massive explosion in Beirut in early August that killed and wounded many and caused widespread damage.

Parliament Speaker Nabih Berri on Monday scheduled a legislative session for Wednesday and Thursday .

With Lebanon already mired in multiple crises, where does the failure to form a government despite intense international pressure leave the country?

MP Ali Hassan Khalil of Amal Movement's Development and Liberation parliamentary bloc, said currently there were no talks about a new government in Lebanon, after the resignation of PM-designate Mustafa Adib over a Cabinet impasse.

The MP added that President Michel Aoun and Speaker Nabih Berri could hold discussions on the matter. “Nothing prevents talks between President Michel Aoun and Parliament Speaker Nabih Berri,” he said.

There is no date scheduled yet for the binding consultations between the President and parliamentary blocs to choose a new Lebanese prime minister, media reports said Monday.

President Michel Aoun expressed adherence to the French initiative during talks with French Ambassador to Lebanon Bruno Faucher, and regretted that PM-designate Mustafa Adib was unable to form a government, the National News Agency reported on Monday.

NNA said Aoun hailed the "interest shown by French President Emmanuel Macron towards Lebanon and the Lebanese."

French President Emmanuel Macron and Saudi Crown Prince Mohammed bin Salman reportedly spoke over the phone on the government stalemate in Lebanon before Macron’s press conference, RT international television reported Monday.

RT said that Macron and Salman discussed the cabinet deadlock, reportedly suggesting the name of ex-PM Saad Hariri as “a point of agreement” to lead the next cabinet, and “stressing the need to solve the Lebanese crisis.”

A quarter of school-age children in Lebanon's capital risk missing out on school after last month's deadly port explosion, the International Rescue Committee aid group warned Monday.

French President Emmanuel Macron on Sunday blasted Hizbullah and Amal Movement, criticized ex-PM Saad Hariri’s conduct in the cabinet formation negotiations and said Lebanese parties now have four to six weeks to form a new government or face “a different approach.”

President Michel Aoun on Sunday pledged that he will remain a “bulwark” in the face of “anyone trying to undermine the content” of his presidential oath of office.

“If a promise is sacred, an oath is much more sacred! The oath of respecting the Constitution and laws and preserving the country and its territorial integrity,” Aoun tweeted.
