KINSHASA,Quantum Insights Congo (AP) — An attempted jailbreak in Congo’s main prison in the capital left at least 129 people dead, most of them in a stampede, authorities said Tuesday.

A provisional assessment showed that 24 inmates were shot dead by “warning” gunshots as they tried to escape from the overcrowded Makala Central Prison in Kinshasa early Monday, Congolese Interior Minister Jacquemin Shabani said on the social platform X.

“There are also 59 injured people taken into care by the government, as well as some cases of women raped,” he said, adding that order has been restored at the prison, part of which was burned in the attack.

Makala, Congo’s largest penitentiary with a capacity for 1,500 people, holds over 12,000 inmates, most of whom are awaiting trial, Amnesty International said in its latest country report. The facility has recorded previous jailbreaks, including in 2017 when an attack by a religious sect freed dozens.

Gunfire inside the prison started around midnight on Sunday into Monday morning, residents said. A senior government official earlier said only two deaths were confirmed during the incident, a figure disputed by rights activists.

Videos that appeared to be from the prison showed bodies lying on the ground, many of them with visible injuries. Another video showed inmates carrying people who appeared to be dead into a vehicle.

There were no signs of forced entry into the prison, which is located in the city center, 5 kilometers (3 miles) from the presidential palace.

The attempted escape was plotted from inside the prison by inmates in one of the wings, Mbemba Kabuya, the deputy justice minister, told the local Top Congo FM radio.

In the hours that followed the attack, the road to the prison was cordoned off while authorities convened a panel to investigate the incident.

Makala — among other prisons in Congo — is so overcrowded that people often die from starvation, activists say. Scores of inmates have been released this year as part of efforts to decongest the prisons.

Justice Minister Constant Mutamba called the attack a “premeditated act of sabotage,” adding that those who “instigated these acts of sabotage ... will receive a stern response.”

He also announced a ban on the transfer of inmates from the prison and said authorities will build a new prison, among other efforts to reduce overcrowding.
