Possible Causes
By Sunday, June 6 there were already rumours circulating that the explosions were intentionally caused. Defence Minister Nikolai Tsonev said that a fire (such as the one that caused the explosions) could not have accidentally occurred, and if it had indeed been an accident, that "whole blocks of flats would have been toppled". Instead, it was carefully engineered to spare casualties, Tsonev told reporters. He said that information from as far back as 2002 had suggested of wrongdoing at the unit.
Prosecutor General Boris Velchev considers the security of the facility inadequate and intends to investigate why the 1,500 tonnes of munitions were guarded only by two retired servicemen. The commander of the base is also under investigation for improprieties in the auctioning of the products of the dismantling.. On June 10, it became clear that 200 tonnes of munitions had been missing from the warehouses; one version being circulated was that the explosions aimed to cover up wrongdoings.
On Friday, July 11, it became clear that investigations would be carried out on suspicions into the possibility that the explosions were carried out on land due to be privatised.
