After examining two reports from the Defence Ministry on the helicopter crash, Serbia’s Prosecution Office on Friday said the crew of the helicopter was primarily responsible.

“There are grounds to suspect that a number of active members of the Army of Serbia bore part of the responsibility as well as indications of possible responsibility of a certain number of civilians,” the prosecution said, without releasing further details.

The prosecution noted that these are only “initial findings” gathered in the first phase of investigation and said it would continue working on the case.

Following the prosecution press release, the Defence Ministry announced it would publish both reports compiled by commissions tasked with investigating the crash.

“The findings of both commissions will be published on the website of the Ministry of Defence by the end of the day,” Defence Minister Bratislav Gasic said on Friday.

Seven people, including four crew members, two medical workers and a five-day-old baby died when the army helicopter crashed near Belgrade’s Nikola Tesla Airport around 10.30pm on March 13.

The Russian-made Mi-17 transport helicopter was carrying the baby, which suffered from respiratory problems, to the capital for treatment after an ambulance taking the child to hospital was blocked by a landslide.

The Defence Ministry formed two separate commissions to investigate the crash.

The first finished its report on March 18 and forwarded it to the prosecution office, without publishing its conclusions. The second finished its 500-page report on March 30 and submitted it the prosecution a day later, also without informing the public and the families of deceased of the findings.

Military experts, the public and the media have raised a number of questions about the accident, including why the helicopter was allowed to fly in bad weather. They asked why the crew was directed to land at Nikola Tesla Airport amid fog, instead of another location.
