a take from elsewhere (not mine, I'm not informed enough...)

This poor woman became so radicalized, apparently during her university days, that she traveled to Israel with a known terror-linked Islamic organization called ISM.

The group she was with began acting violently toward IDF soldiers, forcing the soldiers to respond with live fire. Aysenur appears to have been fatally shot during the confrontation.
This is ISM's typical tactic. Just like with Rachel Corrie, they will use this tragic incident solely for propaganda purposes.
They only care about these activists when they're dead and can be used to demonize Israel.
