The Australian Federal Police (AFP) and Dutch police and prosecutors investigating the cause of the crash of Malaysian Airlines MH17 believe the Dutch Safety Board (DSB) has failed to provide “conclusive evidence” of what type of munition destroyed the aircraft, causing the deaths of 283 passengers and 15 crew on board. Testifying for the first time in an international court, Detective Superintendent Andrew Donoghue, the senior Australian policeman in the international MH17 investigation, said a “tougher standard than the DSB report” is required before the criminal investigation can identify the weapon which brought the aircraft down, or pinpoint the perpetrators.
