Tanzanian prosecutors charged two government officials on Friday with economic sabotage after they were accused of undervaluing an export-bound consignment of diamonds seized from a mine majority owned by London-listed Petra Diamonds. Archard Kalugendo, director of the State-run diamond and gemstone valuation unit, and government gemstone valuer Edward Rweyemamu were jointly charged with being responsible for $1.1-million of lost tax revenue.
