A few parts of the downed Malaysia Airlines (MAS) flight MH17's wreckage, which were too big to be transported by train, has arrived in Kharkiv, Ukraine by truck on Saturday.

The Dutch Safety Board (DSB) in a statement on its website www.onderzoeksraad.nl said other wreckage recovered from the crash site was on its way to Kharkiv, Ukraine, which is more than 300km from Torez, by train.

It said the 12-train wagons with the wreckage on board departed from Torez on Sunday morning.

"When the wreckage arrives in Kharkiv, transportation to the Netherlands will be prepared. At this point it cannot be said when and in what way this transport will be carried out," it added.

On July 17, MAS Flight MH17 was en route to Kuala Lumpur from Amsterdam when the aircraft which was carrying 298 passengers and crew was shot down over eastern Ukraine.

There were 193 Dutch nationals and 44 Malaysians on board, and all Malaysian victims have been identified.

DSB said the recovery of the wreckage started on Nov 16, and recovered as many wreckage within the realms of possibility, at the crash site as possible for the investigation.

"Despite the complex circumstances and local safety situation, the team was able to work as planned under the guidance of Organisation for Security and Cooperation in Europe (OSCE)," it added.

It said the team was supported by local services and the work was done in good cooperation.

Although this recovery operation has ended, it said that there was still wreckage left at the crash site, and the local services will remove those pieces of wreckage from the crash site, as agreed by the recovery team.
