Haunting images show a child’s dust-covered hand reaching out for help from beneath a pile of rubble in Syria three days after a catastrophic earthquake devastated Turkey and Syria — as the death toll topped more than 20,000 people Thursday.

A young boy named Moaz was met with booming cheers as rescuers pulled him out alive from the devastating wreckage in Jindires, in northern Syria, sobering photos and video show.

“We were in a five story building full of people and my whole family died,” the young boy reportedly told first responders.

Hundreds of other families were still stuck under the debris Thursday after about 90 buildings collapsed in the Syrian town, according to the Syrian Observatory for Human Rights.

The catastrophic 7.8 magnitude earthquake hit early Monday morning.

In Syria’s second-largest city, Aleppo, harrowing footage published by Shaam Network shows heartbroken families carrying the remains of deceased loved ones to a mass makeshift burial. One man can be seen carrying a small bundle wrapped in white, appearing to be a dead child.

The gut-wrenching clip then shows all the dead lined up next to each other on the ground as men form graves using stones. An excavator was used to cover the graves, which were then labeled with a black marker.

Also in Aleppo, rescue workers pulled seven people out alive and 44 bodies from a collapsed building in the city center on Thursday, state TV reported.

“We are racing against time. Time is running out,” said the Syrian paramedic group in the rebel-held northwest known as White Helmets. “Every second could mean saving a life.”

In Turkey, dozens of people scrambled for aid in front of a truck distributing children’s coats and other supplies in the southern city of Antakya Thursday.

The US State Department confirmed three American citizens were killed in the quake, and according to local reports, a Queens family of four was also tragically killed in Turkey while visiting family for the month. 

State Department officials could not confirm to The Post whether the New York City family was part of the confirmed fatalities.

Tens of thousands of people in Turkey have lost their homes and have found shelter in tents, stadiums, and other temporary accommodations, others have spent the nights outdoors.

One survivor in Antakya, Ahmet Tokgoz, called on the government to evacuate people from the wrecked region.

“Especially in this cold, it is not possible to live here,” he said. “If people haven’t died from being stuck under the rubble, they’ll die from the cold.”

In the Turkish town of Elbistan, rescuers formed human chains as they dug through collapsed buildings, urging people to be quiet in the hopes of hearing stifled cries for help — though they have mainly only been recovering dead bodies.

Turkey’s disaster management agency said more than 110,000 rescue personnel were now taking part in the effort and more than 5,500 vehicles, including tractors, cranes, bulldozers and excavators had been shipped.

But the scale of loss is unfathomable. Turkish authorities said late Thursday that the death toll had risen to more than 17,134 in the country, with more than 64,000 injured. On the Syrian side, which includes in government-held and rebel-held areas, at least 3,317 have been reported dead and more than 5,000 injured.

The overall death toll has now surpassed the tally in a 2011 earthquake off Japan that triggered a tsunami, killing more than 18,400 people.

Meanwhile, officials expect the grim count to continue to rise, as aid efforts in both Turkey and Syria have been hindered by the lack of machinery and equipment needed to move some of the heavy concrete that has been trapping people, oftentimes fatally.

Rescue missions in Syria have also been slowed by the ongoing war and isolation of the rebel-held region along the border, which is surrounded by Russia-backed government forces.
