As the people of Beirut clean up, France's Macron urges world leaders to come together for Lebanon

However, the French President made clear that reforms were also needed.

"The explosion of August 4 was like a thunderbolt. It's time to wake up and take action," he said. "The Lebanese authorities now have to put in place the political and economic reforms which are being called for by the Lebanese people which is the only thing which will allow the international community to act efficiently side-by-side with Lebanon in its reconstruction."

Macron also thanked Trump and 15 other heads of state for getting involved. The French President added that Israel had also expressed a desire to provide aid.

Seeking to rebuild

After a traumatic week, many of Beirut's citizens flooded outside to clean, sweep and help begin the devastated city's recovery.

"This action, the act of collective mobilization and cleaning, proved that Lebanon is for all, the Lebanese people are the government, they, we are handling this better than the government, look around," said Andrew Trad, 25.

A group of Ethiopian men and women were heading from the Gemmayze neighborhood to downtown to help with the clean-up. Two of them, Zeina and Ameli, stopped to sweep up glass and rubble from the street on their way. "We are doing this because we love this country, it's been our home for years, it's our responsibility to help the Lebanese too," they said.

Berj Dakesian, 70, told CNN he was born and raised in Beirut and wanted to help the city recover.

"I witnessed many wars in Lebanon, but I don't think that I will ever forget the sound and the scene of this explosion in Beirut. My house and my son's house in the same building are destroyed, we cleaned what we can clean but now we are trying to help our community here too," Dakesian said.

Meanwhile, restaurant chain owner Sherif Doumit said he was concerned not just for his business but for the economic security of all his employees.

"Even if we want to restore and build, how can we build on moving sand? It's unstable, the whole country, I am just grateful that no one got seriously hurt from our staff and customers," he said.

"This government is making it impossible for the Lebanese to survive or to even be resilient, it's hit after hit. Even if they do resign, what's the point in that? These politicians are merely puppets in the hands of those in higher ranks, moving them around and dictating their actions and decisions."

Mounzaer Hayek, who is Syrian-Lebanese, said he has lived in the country for 40 years, building up his small jewelry business.

"Now it's all gone. I just want someone to make up for me, no matter what the amount, we need to try and stand on our feet again," said Hayek, 67. "I was in the shop with my son, Lian, when it happened -- I think this glass and wood door saved me. I sustained small injuries, but our business might not survive."

Others were in the downtown area on Sunday looking for vital supplies.

Christine Tawil, who's Syrian, said she had come from Burj Hammoud, northeast of the city, to find aid and food for herself, her parents and two brothers. "Our whole house was damaged," she said. "I now worry that because we are Syrians, our loss won't be prioritized. This explosion was the last horror that Syrians who are taking shelter in Lebanon needed."

And Maria Mouawad, 30, said she had walked from the city's Basta neighborhood to find donations of milk, sugar and other essentials.

"My house is damaged but we are still sleeping inside of it, we don't have any other solutions," she said. "I hate this government, it's still taking away things from us even though we have nothing, we really have nothing."

Mock gallows

While some protests and small riots continued into Sunday, there was little of the outright violence that characterized earlier demonstrations.

On Saturday, dubbed "Judgment Day" by protesters, demonstrations had stretched to surrounding neighborhoods and the city's main motorway, in the biggest outpouring of discontent since a nationwide uprising last October.

Protesters occupied the foreign ministry, the environment ministry and the economy ministry as they called for the ruling elite's downfall. The Banking Association, which protesters blame for the country's worsening banking crisis, was also taken over by demonstrators and set ablaze.

Parts of the demonstrations remained peaceful, while other parts were predominantly filled with angry protesters who faced off with security forces. Police fired tear gas and rubber bullets as protesters hurled stones and fireworks.

In a Twitter statement on Sunday, the Lebanese Internal Security Forces (ISF) denied using live fire and rubber bullets during the protests which left more than 200 people injured, according to the Red Cross.

Unverified pictures and videos circulating on social media showed plainclothes men firing shotguns and pistols. However, the security forces' statement said that one person filmed shooting in the direction of protesters in the videos was not a member of the ISF. CNN cannot independently verify the authenticity of these pictures and videos.

"The directorate confirms that the reporting is not true and that the person is not a member of the Internal Security Forces. Emphasizing that the Internal Security Forces did not fire any kind of bullets while maintaining security downtown Beirut," the statement by the Lebanese ISF said.

Some demonstrators erected mock gallows, a key symbol of the demonstrations. Effigies of prominent political leaders, including former Prime Minister Saad Hariri and Hezbollah chief Hassan Nasrallah, were hanged from nooses, in some of the most explicit signs of public outrage the country has seen in years.

Protesters say that a new generation of Lebanese youth should now be running the country. They are planning more demonstrations and more occupations of government buildings starting Tuesday -- the one week anniversary of the catastrophic port explosion.

Faced with calls to step down, Lebanon's Prime Minister Hassan Diab has vowed to hold early elections. He said he would remain in government for two months until major parties can reach an agreement.

Diab also addressed the country's ongoing political and economic crisis in a televised speech over the weekend. "We need a national solution. We took over the country during an exceptional time... what happened was due to corruption and mismanagement," he said.

Lebanon's Minister of Information, Manal Abdel Samad, announced her resignation Sunday, telling a televised press conference "our reality has not lived up to our aspirations."

Abdel Samad was part of a new cabinet appointed in January after the resignation of the previous government following mass protests last year.

Security officials face questions

Thousands of tons of ammonium nitrate are linked to the catastrophic explosion in Beirut's port. Multiple government agencies in Lebanon were repeatedly warned about the substance, described by an analyst as a "floating bomb," CNN learned.

Lebanese judge Ghassan El-Khoury will resume hearings with the heads of the security services on Monday to examine technical information around the circumstances of the explosion, NNA reported Sunday.

The military police continue to question security officials in Beirut's port as part of investigations into the explosion, under the supervision of the Public Prosecution Office, according to NNA.

Authorities have detained 16 people in connection with the blast, including Director General of Lebanese Customs, Badri Daher, the head of Beirut Port, Hasan Kraytem and the former head of customs Chafic Merei.
