Prince Harry has praised the efforts of the Halo Trust in Ukraine after more than 17 million Ukrainians saw videos made by the charity which educates them on how to stay safe from unexploded ordnance.

The Duke of Sussex, 37,  held a video call with two women who have made the decision to stay in Ukraine with the Halo Trust which has been clearing military ordinance in the eastern European country since 2016.

Princess Diana worked with the Halo Trust in Huambo, Angola, during the 1990s in a fight against landmines.

At the time, her support for an international treaty banning use of the explosive devices was seen as a political stance, but it was widely regarded as one of her greatest humanitarian efforts.
