Black Tulip is a Ukrainian organisation that has been working for more than a decade to find and identify bodies of missing soldiers from the First and Second World Wars.

Its work is now focused on finding the hundreds of missing Ukrainian servicemen from the current conflict in the east of Ukraine.

With the consent of the authorities in rebel-held territory, the group is able to cross the frontline and travel to sites where it believes soldiers might have gone missing.

So far Black Tulip has found and identified 613 bodies of dead soldiers. It says that between 300 and 1,500 are still missing.

However Black Tulip says its valuable work, which helps the relatives of the fallen grieve, might have to stop because of a lack of funding.
