A couple from the UK, International Construction volunteers, were living in a trailer whilst building a translation facility in Mozambique. A gang attacked them with machetes and stole everything they owned.
The couple were flown back to the branch in South Africa. The SA branch organizes WT building projects for the whole of Africa. The second most senior overseer in the building department went immediately back to Mozambique to organise better security. The gang came back and shot the overseer to death.
I offer this story without embellishment or comment though I believe it to be true. Can anyone confirm or deny it?
