Protesters demand justice over the nightclub fire that killed 63 people in the town of Kocani in March.

Thousands of protesters have marched in North Macedonia’s capital, Skopje, demanding justice for the 63 people who were killed in a fire at a nightclub in March.

The rally on Saturday comes ahead of the trial of the 34 people and three companies charged over the incident, which marked the deadliest blaze in North Macedonia’s history.

The fire broke out at the crowded Pulse club in the eastern town of Kocani during a hip-hop concert on March 16, triggering a stampede and killing 63 people. Some 200 others were injured.

Most of the victims were aged between 16 and 26.

Families of the victims and their supporters marched to the North Macedonian parliament on Saturday, dressed in black and carrying a huge banner with pictures of the victims, saying, “63 shadows will be following you”.

The protesters also chanted “justice for Kocani”.

The families blame corruption and greed for the deaths of their children at the unlicensed venue in Kocani. Authorities said the fire was sparked by a pyrotechnic flame that engulfed the roof of the club and that the venue had numerous and serious safety violations.

Natalija Gjorgjieska was among the families demanding justice on Saturday.

Her husband, musician Andrej Gjorgjieski, was killed in the fire. “We demand the truth. Where did the mistakes occur, who didn’t respond, which institutions were late, who had the responsibility to prevent [them] and did not?” she said.

The prosecution filed indictments for 34 people, among them the club owner, security guards and former mayors of Kocani, as well as representatives of three legal entities, including the security firm and the club owner’s companies.

They are accused of “serious crimes against public security”.

Other defendants include inspectors, civil servants and former economy ministers. If found guilty, they face up to 10 years in prison.

Corruption has long plagued North Macedonia. The Berlin-based monitor Transparency International ranked North Macedonia in 88th place globally on its Corruption Perception Index last year, one of the worst rankings in Europe.

Bribes to authorities to skip licensing requirements and skirt safety regulations are commonplace.

The European Union has repeatedly expressed concerns over pervasive corruption in the country, identifying it as a major obstacle to the nation’s accession to the bloc. North Macedonia is a veteran candidate country, waiting for entry into the EU since 2005.
