Almost one year after the MH17 air disaster, no trace has yet been found of two of the Dutch victims, according to forensic experts.

Army experts have been identifying the remains of the victims since August 2014 and 296 people have been named. But no dna traces have yet been found of Alex Ploeg (58) and Gary Slok (16), news agency ANP reports.

There is no doubt that both were on board the Malaysia Airways plane, which was brought down by a missile over eastern Ukraine, officials say.

For example, Slok put a photograph of himself and his mother starting their journey on Facebook. Ploeg was on board with his wife Edith and son Robert, who were identified in November.

Now the dna investigation is winding down, family members can claim the rest of the remains of their loved ones for burial or cremation.

Some samples which did not issue any usable dna are being preserved so that they can be looked at again when new techniques have been developed.
