"We are confident that we have enough evidence not only to determine the cause of the disaster, but also to identify the perpetrators," he said.
At the same time, the press officer did not name possible time frame necessary for the completion of work on the collection of evidence and eyewitness testimony by the international group, but stressed that as of now over 100 professionals are working on it.
According to him, a criminal investigation into the downing of flight MH-17, which is conducted the Prosecutor's Office of the Netherlands, together with international partners, will continue at least until the end of the current year. "There is no specific time frame. This is an international investigation, which is carried out in difficult conditions, so it will require more time. It will continue at least until the end of the year," Wim de Bruin said.
He added that there are no formal conclusions at the moment, since "the investigation is ongoing."
In December, 2014 international experts conducted search operations at the crash site of the Malaysian Boeing flight MH-17 shot down by separatists in Eastern Ukraine on July 17. The experts have collected fragments necessary for the reconstruction of the aircraft within the framework of the investigation. They are currently located at the Dutch Air Force Base Gilze-Rijen, where expert analysis and three-dimensional reconstruction of the aircraft will be conducted.
