Mysterious CIA chip
That success is reportedly in part thanks to the mysterious electronic devices, dubbed “chips” or “pathrai” (the Pashto word for a metal device), which have become a source of fear, intrigue and fascination.
“Everyone is talking about it,” said Taj Muhammad Wazir, a student from south Waziristan. “People are scared that if a pathrai comes into your house, a drone will attack it.”
According to residents and Taliban propaganda, the CIA pays tribesmen to plant the electronic devices near farmhouses sheltering al-Qaida and Taliban commanders.
Hours or days later, a drone, guided by the signal from the chip, destroys the building with a salvo of missiles. “There are body parts everywhere,” said Wazir, who witnessed the aftermath of a strike.
Until now the drone strikes were the only threat to militants in Waziristan, where the Pakistani army had, in effect, abandoned the fight.
But now, emboldened by a successful campaign to drive militants out of Swat, a region about 80 miles from Islamabad, the army is preparing to regain lost ground in the more remote tribal belt.
