Israel Police have begun implementing a new method of searching Palestinian vehicles through use of nausea-inducing chemicals at a Bethlehem checkpoint, international aid workers have reported.
Since December, Israeli police officers have introduced what they call a sophisticated method of tracking explosive materials.
Palestinians with Israeli license plates, usually residents of Jerusalem or foreign residents are allowed to pass through the checkpoint. Cars traveling to Jerusalem are often asked by Border Police soldiers to park their car in a side lot with eight parking spaces near the checkpoint.
Once parked, the passengers are asked to roll up all windows, apart from that of the driver – and exit the vehicle. Two tubes are then connected to the vehicle – one is connected to an air pump, the other, which passes through a tiny filter, is attached to the vehicle. A policeman with a stopwatch flicks the air pump switch.
