Fire ripped through a packed nightclub early on Sunday in the North Macedonian town of Kocani, killing 59 people and injuring more than 150, officials said, after sparks ignited the roof above a live band.

Authorities arrested about 20 people in connection with the fire, including government officials and the manager of the “Pulse” nightclub, which did not have a legitimate licence, Interior Minister Pance Toskovski told a press conference.

“We have a reason to suspect graft and corruption were involved in this case,” he said, without providing details.

One video from the event, verified by Reuters, showed a band playing on stage flanked by two flares whose white sparks set a patch of ceiling alight. The fire spread fast and caused a panicked rush to the exits.

“Fire broke out, everyone started screaming and shouting: ‘Get out, get out’,” Marija Taseva, 22, told Reuters.

As she tried to escape, Taseva fell to the ground and people trod on her, injuring her face. In the rush, she lost contact with her sister, who did not make it out.

“My sister died,” Taseva said, breaking into tears.

Toskovski confirmed that the fire, which began at around 3 a.m. (0200 GMT), was caused by “pyrotechnic devices” whose sparks triggered the blaze. He said 500 people were in the club when the fire started.

About 148 people were hospitalized in Skopje, Kocani and surrounding towns, Health Minister Arben Taravari said, adding that 20 people were critically injured.

Condolences flooded in from global leaders, including EU commission president Ursula von der Leyen and Pope Francis.

People searched for missing loved ones online and at hospitals across the country.

Simeon Sokolov, 50, found his daughter Anastasija at the emergency ward of the September 8 hospital in the capital Skopje, where she was being treated for burns and smoke inhalation.

“I just know that there are many children who have suffered,” he told Reuters. “Doctors are doing their job and the number is big.”

Some patients were transferred to neighbouring Bulgaria, Serbia and Greece for treatment, authorities from those countries said.

INVESTIGATION

North Macedonia’s Public Prosecutor Ljupco Kocevski said five prosecutors would investigate the incident.

“At the moment, orders have been issued for collecting of evidence” and some people were being interviewed, Kocevski said, without elaborating.

Toskovski said authorities had arrested members of the band, the son of the club owner and government officials.

Firefighters doused the charred and smoking entrance of the “Pulse” nightclub before dawn as ambulances rushed from the scene, TV footage from a local broadcaster showed.

Reuters pictures showed the club’s corrugated iron roof burned through and collapsed in places, its interior wooden beams exposed and blackened.

North Macedonia Prime Minister Hristijan Mickoski said on Facebook: “This is a difficult and very sad day for Macedonia! The loss of so many young lives is irreparable, the pain of the families, loved ones and friends is immeasurable.”

After visiting the injured in a hospital in Skopje, North Macedonia’s President Gordana Siljanovska Davkova, dressed in black and fighting tears, said authorities were ready to do everything to help all affected.

“I simply cannot comprehend this … what a disaster, what a tragedy.”
