Even though the terrorists have been trying to hide the tunnel entrances, by blindfolding the diggers and the reporters they are bringing to display their handiwork, apparently the Israelis have been able to pinpoint the entrances to the tunnels by following their cell-phone signals.
When the evil Zionists see the signal disappear in the middle of a house, they know that the phone has just gone deep underground to where the signals do not reach.
So Islamic Jihad recommends that all terrorists turn off their phones far from work.
They also urge fellow terrorists who read Palestine Today to change their SIM cards and phones from time to time to frustrate the nefarious Zionists.
Too bad that they cannot communicate by land lines or by cell phones. Maybe they should learn smoke signals. After all, they claim to be just like Native Americans.
