Myriam Sassine, a Beirut-based film producer, said Hariri's return showed there is nothing but "disappointment and heartbreak" in Lebanon.
The General Directorate of the Presidency of the Republic of Lebanon, announced in a statement, read by Director General Antoine Choucair, that "President Michel Aoun, having conducted the binding parliamentary consultations and consulted with Parliament Speaker Nabih Berri to inform him of their official results, has summoned PM Saad Hariri to assign him to form a new government".
He faces the grueling task of forming a cabinet in a country still reeling from the aftermath of a massive explosion that ripped through the capital in August.
Hariri is likely to be re-elected as prime minister given that his allies hold a slim majority in Parliament and there are no other viable candidates at the moment.
Hariri vowed Thursday to quickly form a new Cabinet of nonpartisan specialists.

Any new government will have to contend with a financial meltdown worsening by the day, a COVID-19 outbreak and the fallout of the massive explosion at Beirut port that killed almost 200 people in August.
He said he would form a cabinet of "non politically aligned experts with the mission of economic, financial and administrative reforms contained in the French initiative roadmap". Its priority is to resume talks with the International Monetary Fund for a desperately needed bailout, amid rapidly shrinking foreign currency reserves. His father, former Prime Minister Rafik Hariri, was assassinated in office.
Hezbollah, the militia and political faction that is backed by Iran, now has control over Lebanon's affairs.
The country has since been without a cabinet due to continuing political discord.
The former, and now new, Prime Minister (of the Future current) had to give in to a popular movement born on 17 October 2019 demanding the departure of all politicians in power, as they were deemed incompetent and corrupt.
To help address the issues on the table, Hariri's government is expected to resume talks with the IMF for a bailout, although the worldwide community earlier cautioned that it was hesitant to provide support before reforms are implemented. The day before, without naming him explicitly, the president had warned that Mr. Hariri would have the heavy responsibility of fighting corruption and launching reforms.
The process can take months in Lebanon, where consensus between most of its top political groups is required for major decisions. Hariri's supporters also set fire to a large depiction of a fist that symbolizes the uprising against the old political class.
