Diarrhoea and other deadly waterborne illnesses threaten some 28,000 Chadians in an eastern town, after armed attacks – including the theft of a water pump – forced out the last aid workers running already scaled-down operations. UN aid officials fear that people will begin to flee the area – Dogdore – if aid operations do not resume there soon, thus further complicating humanitarian efforts in Chad's volatile east. About 24,500 displaced Chadians live in Dogdore, along with some 4,000 local residents, according to the UN.
