Israel checking: Was drone headed to Dimona?

After Israeli fighter jets shot down a drone over the Yatir forest in the south Mount Hebron area on Saturday, the army is trying to figure out what its destination was. One of the possibilities the security establishment is looking into is that the unmanned aircraft, which was apparently Iranian-made, was on its way to test the option of infiltrating the nuclear reactor in Dimona, perhaps even to examine the option of targeting the plant in a future conflict.

One odd thing about the video of the Israelis shooting down the drone: the plane shot it with a missile at very close range. Why bother getting that close when the missile probably has a range of a mile or better.
