Mo, Evie and Otis Maslin, aged 12, 10, and eight, all died on flight MH17 along with their grandfather Nick on July 17.
In what is now their last message, the happy and smiling youngsters ride their bikes and swing on a roundabout telling their auntie they will see her next year.

A woman has apparently posted pictures of herself on social media with mascara looted from the Malaysian Airlines flight MH17 crash site.
A large section of plane wreckage and everyday carry-on items like chocolates remain scattered among the wild flowers at the crash site.
