It was not clear why the Pakistani soldier had opened fire in the incident

Oh, I think its clear:

I-S-L-A-M

No, more like Pakistan is harboring the Al -Qaeda much like Afghanistan did.

I would bet dollar to dognuts that these are the same guys that fired on US troops last week. The Pak military is full of Taliban/Al-Qaeda sympathizers (and probably members too..)
