TAVETA, Kenya, July 19 (Reuters) - The Trump administration's decision to slash nearly all U.S. foreign aid has left dozens of water and sanitation projects half-finished across the globe, creating new hazards for some of the people they were designed to benefit, Reuters has found.

Reuters has identified 21 unfinished projects in 16 countries after speaking to 17 sources familiar with the infrastructure plans. Most of these projects have not previously been reported.
