Mexican soldier clear the road in Hidalgo on May 29, 2002, where
authorities found 70 barrels of deadly sodium cyanide, part of a large
shipment that was stolen from a truck earlier this month and set off
fears it could be used by terrorists. U.S. customs officials issued a
series of alerts about the stolen truck on the U.S-Mexico border and
scrutinized vehicles for the cyanide, with concerns it could be put
into water supplies or otherwise used in a terrorist attack.
