Monitors from the European security body OSCE and Malaysian inspectors say they have found parts of the fuselage of downed Malaysia Airlines flight 17 with “significant puncture marks”.

“Some of the materials we saw and have photographed feature significant puncture marks to the fuselage, almost a piercing mark,” said Michael Bociurkiw, spokesman for the Organisation for Security and Cooperation in Europe’s special mission to Ukraine, on Wednesday.

These parts “were looked at by the Malaysians and I can say that these parts were of very great interest to them,” he said, adding that the team had also spotted human remains still lying at the crash site.

Dozens of victims of the flight are still formally unaccounted for, as the first bodies in 40 wooden coffins arrived in the Netherlands on Wednesday.

Out of the 298 people on the downed plane, 193 were Dutch.

Reporters near the crash site also saw what appeared to be part of the fuselage with puncture marks, resembling the damage left by shrapnel.
