At least 50 people have been killed in a nightclub fire in North Macedonia in the early hours of Sunday, according to the state news agency, citing the interior ministry. More than 100 people were said to have been injured.

The fire reportedly broke out around 03:00 (02:00 GMT) during a performance by hip-hop group ADN at the Pulse club in Kocani, a town around 100 km (60 miles) east of the capital, Skopje.

The injured were taken either to the local hospital in Kočani or to Stip, about 20 miles south.

North Macedonian interior minister, Panche Toshkovski, has been speaking to journalists at a press conference following the deadly nightclub fire.

The concert, attended by as many as 1,500 fans, at the Pulse club was full of mainly young people.

Toshkovski said some of the young clubgoers used pyrotechnics that caused the roof to catch fire, according to the Associated Press.

He told the press conference that police have arrested one man, but didn’t provide details on the person’s involvement. We have not been able to independently verify this information yet.

Prime Minister Hristijan Mickosk has expressed “deep sadness” about the “tragedy” of the nightclub fire. He said the loss of so many young lives is “irreparable” as he extended his condolences to the family and friends of those who were killed in the blaze.

Mickosk wished those injured a speedy recovery and said the government is “fully mobilised” to help determine the cause of the fire.

“I call on all competent institutions – health services, police, local authorities – to take urgent measures to assist the injured and support the affected families,” he said in a statement posted to Facebook.

“During the day, after reviewing the circumstances from the competent institutions, I will address the public with more information about the steps taken,” the prime minister added.

“In these times of deep sadness, when our hearts are broken with pain due to this terrible tragedy, I call for unity, solidarity, humanity and responsibility.”
