The drone shot down by pak is a chinese made one -
DJI phantom
and recently pak police bought these drones from chinese company...
the 2nd pic is of a pak police personnel holding dji phantom look closely both at the pics ..those are the same drones..
while Indian army and indian forces use DRDO made netra drones...
look at the wings they are facing down, while those in the alleged pak shot drone the wings are on top..
coming to your last question.. DJI phantom has a range of only 2km.. the drone was shot down at a place 50 kms away from LOC.. hardly near the border and well within pak territory.. there is no way India would operate a 2km range drone staying away from 50 kms..
