As their captors sought cover, the terrified children were ordered to stay and shoot down the jets over the capital, Khartoum. If they tried to flee, they’d be killed by their captors, if the planes didn't get them first.
The boy, now 17, told The Associated Press that those who ordered him strapped to the gun were Colombian mercenaries providing military aid to the Rapid Support militia against the Sudanese National Army in the war, now in its fourth year.
Another child said he was forced to carry out artillery strikes and beaten for disobedience.
The rare, firsthand accounts show the perils faced by tens of thousands of children believed to have been conscripted into the war.
Six former child soldiers who were abducted and forced to fight with the Rapid Support militia, known as the RSF, spoke to the AP on condition of anonymity for fear of reprisal. Two said they were trained by Colombians.
Their accounts point to a wider deployment of Colombian mercenaries, whose rights groups say were recruited by a state-linked firm in the United Arab Emirates to fight with the Rapid Support militia.
Human rights groups and Sudan's military accuse the UAE of arming the RS militia, and a UN panel said it had tracked weapons shipments to the RSF originating in the Gulf federation that includes Dubai.
The UAE did not respond to multiple requests for comment. It has previously denied arming the RS militia, saying the shipments in question were of humanitarian aid for refugees.
The boy who had been shackled to the gun burst into tears as he ran his hand over scars from the some 18 months he was forced to fight.
“I was extremely scared. I just wanted to escape and go home,” he said.
The children were shackled day and night
He said he was rounded up by Rapid Support fighters in a market in Khartoum's twin city of Omdurman, where he was selling cigarettes. The militia were searching for deserters and seized him by mistake, he said. He was 15 at the time.
Never having held a gun, he was thrust onto the front lines in Khartoum. Scars on his head and under his eye mark where he says he was hit by shrapnel.
He was later taken to an RSF base in Omdurman known as Central Reserve Camp, where he was held with dozens of other children. Their hands were bound all the time, even while eating.
“We weren’t allowed to bathe. Instead, they would pour water over us while we were still bound,” he said.
He said dozens of foreign mercenaries were at the base, described as Colombians by the Rapid Support fighters there.
Speaking through translators, they taught the children how to use anti-aircraft guns. They told Rapid Support fighters to bind the children to the weapons so they couldn’t escape, he said.
“When the planes flew overhead, the Colombians would retreat to their bunkers, leaving us outside shackled to the vehicles,” the teenager said. He was forced to fire, but he said he was too afraid and never hit anything.
A second boy recounts beatings, and a friend's killing
The second boy described how, at age 15, he was held at an Rapid Support militia camp called al-Konan, where he said Colombians trained him and other boys on heavy artillery and drones.
He said he was locked up and only brought out for artillery strikes. The Colombians and the RSF militia used drones to choose targets, and sometimes he saw civilians through the camera. When he refused to fire, they would beat him, sometimes with an electric baton. In one case, he said, a Colombian beat him unconscious.
An 18-year-old friend tried to flee and was shot dead by the militia. He carried the body away.
“I still have nightmares whenever I try to sleep,” he said.
Both children spoke at a facility run by the military-backed government on Khartoum’s outskirts, where more than 200 former child soldiers were being rehabilitated. Many fell into the hands of the military when it retook the capital from the RSF over the past year.
A member of the military media office accompanied the AP during the visit. The official did not choose who the AP interviewed.

Veterans of Colombia's long wars have hired themselves out
The AP could not independently verify the boys' accounts, which are consistent with other reporting on the conflict.
Multiple countries are entangled in Sudan's conflict, and other foreigners, including Russians and Ukrainians, have taken part in hostilities.
Some 10,000 Colombians have hired themselves out for foreign wars, including in Somalia, Ukraine and Sudan, according to the UN Colombia's decades of internal conflict, involving guerrillas, paramilitaries and drug traffickers, have produced a large cadre of veterans prized for their US-backed military training and driven abroad by meager pensions and scarce civilian job prospects.
A recent law bars Colombians from fighting in foreign conflicts, but veteran groups say recruitment has continued.
Human Rights Watch and Conflict Insights Group, a private research firm, have documented the presence of Colombian mercenaries alongside the Rapid Support militia in Sudan's western region of Darfur, including during the October capture of El Fasher, where RS fighters have been accused of mass killings.
In separate reports this year, Human Rights Watch and Conflict Insights Group said the Colombians were hired by an Emirati contractor and trained in Emirati military bases. The UAE denied those allegations at the time, telling the BBC it had no involvement in recruiting or training foreign fighters and that it would investigate and prosecute any entity suspected of doing so.
A Colombian mercenary who fought in Darfur for six months in 2025 told the AP that hundreds of Colombians were on the front lines with the RS militia at the time and involved in training recruits. He said he saw children as young as 13 fighting with the militia.
He spoke on condition of anonymity, concerned over legal consequences.
Less is known of the Colombians’ role in Khartoum. Ali Qader, the head of the rehabilitation center, said several children told him Colombians trained them at camps around the capital.
A former Rapid Support fighter, who defected to the government side and spoke on condition of anonymity out of security concerns, said he saw Colombians training children in Khartoum in July 2024.
A Sudanese military officer with knowledge of the situation said Colombians were training children in and around Khartoum when the RSF militia held the city. The officer was not authorized to brief reporters and spoke on condition of anonymity.
The Colombian government said it has no official information confirming allegations that Colombians recruited or trained child soldiers in Sudan. It condemned such abuses.
Child recruitment is a war crime
Tens of thousands of children as young as 8 have been recruited during Sudan’s war, according to Abdelgadir Abdullah Abu, secretary-general of Sudan's National Council for Child Welfare, a government body.
The UN says all sides in the conflict have used child soldiers, including militias allied with the government.
Many are believed to still be on the front lines. The Rapid Support militia and the Sudanese government did not respond to detailed requests for comment.
The RSF militia have roots in the Janjaweed militias that rampaged across Darfur in the early 2000s. Sudan's then-president Omar al-Bashir was indicted for war crimes and genocide by the International Criminal Court over that campaign.
“The evidence suggests the UAE could be substantially contributing to the RSF’s widespread crimes against humanity,” said Jean-Baptiste Gallopin, a senior adviser at Human Rights Watch.
Children returning from the front often have nowhere to go
At the rehabilitation center, which included a soccer field and volleyball net, boys dressed in white uniforms showed an AP reporter their wounds.
One was missing a hand; another had scars on his back from where he said he was tortured; a third had a bone jutting out of his side.
The boy held at the Central Reserve Camp said that at one point, when tied to the anti-aircraft gun, he refused to fire on a jet. Rapid Support fighters shot at him as punishment, wounding his foot.
The wound filled with worms, he said. Eventually, the fighters abandoned him because of it, and he was later brought to the youth facility.
Wiping away tears, he said he’s aching to return home. His mother died from illness during the war, and his father told him he was ashamed of what his son had done and doesn’t want to see him.
Zeinab Mahjoub, a psychologist at the facility, said she tries to persuade relatives not to abandon the boys. At the same time, the boys are wrestling with their own trauma.
Sheldon Yett, the head of the UN children’s agency in Sudan, said it was working with the government and other parties to speed up the process of releasing the boys, trying to convince authorities to treat “children as children.”
Since the AP visited the center in April, the children have been released.
The boy held at al-Konan Camp said that after nearly two years, he escaped one night when a guard left a door unlocked.
He tried returning to his family but someone in the area knew he had fought with the RSF militia and reported him to the authorities, who referred him to the center.
He’s trying to move on but is wrestling with guilt.
“We have made mistakes,” he said. “We want to get out of here to rebuild Sudan.”
