This is with reference to a most disturbing news which the head of US Senate Intelligence Committee Dianne Feinstein disclosed on February 12 that unmanned CIA predator aircrafts (drones) operating in Pakistan are flown from a base inside that country. Senator Feinstein's revelation is the first US official ever to have made a public comment about the take-off and landing location of the predator aircrafts patrolling Pakistan. She has expressed surprise at Pakistan's opposition to the ongoing campaign of predator launched missile attacks against extremist targets along Pakistan's border with Afghanistan. It is strongly suggested that our government should itself take necessary measures against these extremists and not allow these US drones to assault our territory, wherever their base be, inside or outside Pakistan. -ENGR.
