Hundreds of young Spanish volunteers have been evacuated from Ghana after a row broke out when an aid project they signed up for via Instagram descended into chaos.

Yes We Help, founded by self-styled entrepreneur Yago Zarroca, signed up more than 1000 young people for its promised summer programmes in far flung destinations such as Ghana and Sri Lanka - or so the Barcelona-based group claimed.

Lured by Instagram pictures of smiling volunteers embracing African children and promotional posts from a handful of “Insta-Celeb” influencers, the volunteers paid €850 each for their stays - not including travel, visas or vaccinations.

But participants complained they had arrived to find the projects either in a state of complete disarray, or non-existent.

Supposed leaders were either absent or drawn from the volunteers themselves, while materials or funds needed for projects were missing.

Volunteers complained of being left without beds or food and in some cases accommodation entirely as promised stays were cut short.
