The desperate plea of ​​the people of Aleppo calling for humanitarian aid to the world

A group of people stands proud against a horizon crumbles. The exhaustion of their cause is written on their faces.

Dressed in the uniforms of their trades, the men hold flags of the Syrian opposition, while a woman grabs a baby.

They are a coalition of activists including doctors and civil servants from rebel-held areas of Aleppo.

In an unusual message in English, this group of people sent a desperate plea asking the US-led coalition to send humanitarian aid from the air.

In the video appears a man known as Dr. Hamza al-Khatib, who stands in the middle of the group, takes the floor and speaks in English.

It makes a dark journey of the misery of Aleppo based on figures of that collation of activists:

- 500,000 people killed in six years 
- At least 271,536 people trapped in eastern Aleppo, controlled by the rebels, he says, citing the City Council of Aleppo 
- At least 2,300 bombardments documented in the last 23 days: air strikes, explosive barrels, artillery, cluster bombs, gas-charged bombs 
- 4 hospitals hit in the last week, along with six schools, civil defense buildings and two bakeries.

CNN can not independently verify the death toll in Syria, but the United Nations says the number is 400,000.

Al-Khatib accuses the Russian and Syrian air forces of intentionally targeting civilian infrastructure to "break the will of the people," despite Russia's refusal to attack civilian infrastructure.

People who starve, dying, with little or no access to medical care, are afraid to go to hospitals, he says, for fear of becoming victims of the latest bombings.

The last six years have been a "slow-motion train clash" leaving him and his colleagues wondering what the United Nations is for.The doctor calls on the international community to press for the following:

To ground the Bashar al-Assad air force or use diplomatic influence to end the bombing of Russia and Syria against the city.

Open a demilitarized corridor under the control of the United Nations to bring food, fuel, medicine and infrastructure, as well as supplements for water stations, electricity, hospitals, schools and civil defense.

If this is not possible, they call for the launching of humanitarian aid from the sky using United States-led coalition planes in Syria.

The international community has the fate of Aleppo in their hands, he says. Will he pay attention to their cry?

Asad regime forces recover key neighborhood in Aleppo

Syrian regime forces have entered the east of Aleppo and retook parts of its largest district, launching a ground assault to take control of rebel - controlled area.

The offensive to recover the key area of ​​Masaken Hanano was backed by regime air strikes and marked the first time government forces have retaken a significant part in eastern Aleppo since the rebels seized the area more than four years ago.

Government forces also entered the Jabal Badru neighborhood on Sunday, dividing eastern Aleppo into two.

Aleppo is divided between government-controlled areas in the west and rebels in the east. Bachar al Asad promised to retake the entire city, which was once the commercial heart of Syria and is now one of the last urban redoubts still in the hands of the rebels.

East of the city has become the epicenter of Syria's brutal five-year civil war. Much of it has been reduced to rubble due to the intense bombing of regime forces backed by the Russian air force, while the humanitarian crisis has a catastrophic scale.

At least 46 people were killed and 325 wounded on Saturday when regime forces entered the eastern city, according to Syrian Civil Defense volunteer rescue group, also known as the White Helmets, and activist Aleppo Media Center.

White Helmets said there were at least 150 air strikes and 2,500 artillery shells in and around the city on Saturday.

The Syrian army said Sunday that its units are securing the exit routes of 1,500 people from eastern Aleppo to the regime areas, according to state news agency SANA.

But some civilians told CNN that they were not going to leave Aleppo because they had nowhere else to go. Many say they fear reprisals or be separated from their families.

10,000 people leave Aleppo

About 10,000 people have left rebel-controlled areas in eastern Aleppo in recent days amid sweeping advances by the Syrian army, according to a UK-based human rights watchdog.

About 6,000 people have fled to areas controlled by Kurdish forces, the Syrian Observatory for Human Rights reported Monday.

In addition, more than 3,000 civilians - more than half as children - have fled to government-controlled areas of the city in the last 24 hours, according to Russian and Syrian state media quoting the Russian reconciliation center in Syria which is located in The military base of Hmeymim.

Syrian state news agency SANA reported that "hundreds" more civilians fled to parts controlled by the city government.

"A nightmare without end"

The UN agency for children, UNICEF, reported that about half a million children live in a state of siege in Syria, a figure that has doubled in less than a year.

Children live in 16 areas, deprived of aid and basic services, UNICEF said.

"For millions of human beings in Syria, life has become an endless nightmare - particularly for hundreds of thousands of children living in a state of siege. Children are being killed and wounded, they are too afraid to go to School or even play, survive with little food and almost no medicine, "UNICEF Executive Director Anthony Lake said in a statement.

UNICEF estimates that 100,000 children live under siege alone in the east of Aleppo alone. It is believed that about 250,000 people are trapped there.
