Prime Minister Dr Mahathir Mohamad repeated Malaysia's concerns today regarding the matter of the investigation and stated that Malaysia itself was not allowed access to the black box.
"They are accusing Russia but where is the evidence? We know the missile that brought down the plane is a Russian-type missile, but it could also be made in Ukraine....You need strong evidence to show it was fired by the Russians. It could be by the rebels in Ukraine; it could be Ukrainian government because they too have the same missile...We may not have the expertise but we can buy the expertise. For some reason, Malaysia was not allowed to check the black box to see what happened. We don’t know why we are excluded from the examination but from the very beginning, we see too much politics in it......The idea was not to find out how this happened but seems to be concentrated on trying to pin it on the Russians. This is not a neutral kind of examination. Had a neutral party examined and made the conclusion, Malaysia is willing to accept the findings but here we have parties with political interests in the matter"
