HARARE, Zimbabwe (AP) — Zimbabwe's state media says the people who delivered deadly cyanide — evidently in error — to a main water treatment plant will face charges of the attempted murder "of the people of Harare."

The Herald newspaper said Thursday that drums of cyanide for use in mining and manufacturing were described as purifying chemicals on transportation documents that were attached by mistake. The poison was identified before it was offloaded at the plant, averting a disaster, the paper said.

It said prosecutors ordered a police investigation into how 19 tons of cyanide arrived at the plant on July 25.
