A fragment of the downed Malaysia Airlines (MAS) flight MH17 will be handed over to crash investigators by a Russian veterans group, The Sydney Morning Herald reported Monday.

According to reports, the decision was made after the group, Combat Brotherhood cancelled its plans to display the fragment in a new museum dedicated to Soviet military victory.

Russian news reports said that the fragment of the Boeing 777 had been delivered to the town of Yeisk in the Krasnodar region of southern Russia, for a new exhibition celebrating the end of World War 2.

Combat Brotherhood stated that they had earlier intended the exhibit as 'proof' that Ukraine separatists did not shoot down the plane in July last year.

The move, however drew criticism from Dutch investigators who have been gathering wreckage of the plane to establish the cause of the crash which killed all 298 passengers and crew on board.

The head of the group told Business Yeisk the fragment had been sent to them by locals at the crash site, as gratitude for the humanitarian aid that they had provided.

According to them, it is also to deliver to the public the horrors taking place in the region.

However, the news site reported that the group had "realised that all the pieces of the aircraft are physical evidence", and decided to return it to Ukraine and recommend it be handed over to the international investigators.
