This is not good news.
Something to ponder while awaiting further news/details.
If this plane was hit by small arms while the aircraft was still in the air, rather than on the ground, somebody on board got hit with the veritable "golden bullet" (or Golden BB) in this case.
My point of reference is the almost daily reports of small arms fire at aircraft coming into BIAP back about ten years ago, with nary a fatality save one unlucky Aussie who caught one (on a C-130 IIRC).
