TIJUANA: Nine people in Mexico were caught red- handed on Tuesday digging a tunnel that was apparently to be used to sneak drugs into California, officials said. The detainees had been digging from inside a house in the north- west border town of Tijuana and tried in vain to flee, the National Defence secretariat said. The tunnel was about 20m underground and reachable by climbing down a ladder through a closet in the house. Army troops also seized a truck that the detainces had been using to take away soil from the digging operations. APP 10
