Mexican soldiers have seized two catapults that were being used by drug smugglers to fling packages of marijuana across the border with the US into Arizona. A military statement today says an anonymous tip led troops to a house in the border city of Agua Prieta where they found a catapult in the bed of a pickup truck and another inside the house. It says soldiers also seized 1.3 tons of marijuana during Monday’s raid in Agua Prieta, which is across the border from Douglas, Arizona
