"Four Dutch nationals were at the disaster site, as part of an OSCE team," Justice Ministry spokesman Jean Fransman told AFP. "Trucks are at the scene to take what's found somewhere before they're returned to the Netherlands," he said.
Members of Ukraine's State Emergency Services (SES) are conducting the search for body parts and possessions that resumed on Monday, he said. "Some personal effects have already been collected by the local population," Fransman said. "We hope that this will be done quickly but we will take all the time necessary."
All 298 people on board the flight were killed, two-thirds of them Dutch. Dutch forensic experts called off their search of the area in early August because of the ongoing fighting, with Prime Minister Mark Rutte lamenting the continued lack of access to the site. A fragile truce has been agreed in the area, with Ukrainian and Russian officials trying to shore up the ceasefire.
Flight MH17 was shot down on July 17 while flying over insurgent-held territory in conflict-wracked eastern Ukraine.
The Netherlands is in charge of identifying the bodies and probing what caused the crash. A total of 272 of the dead have so far been identified. The findings of an initial report by a Dutch-led team of air crash investigators appear to back up claims that the plane was hit by an anti-aircraft missile.
Kiev and the West have accused Moscow-backed separatists of shooting it down with a surface-to-air BUK missile supplied by Russia. Moscow denies the charge and has pointed the finger at Kiev.
