Israel and Egypt work to maintain security cooperation after border attack.

The sister of Sgt. Lia Ben Nun, a female soldier killed in a shooting attack on the Egypt border, has criticized Channel 14 for implying impropriety on the part of the male and female soldiers stationed at the targeted post. The news network's coverage of the tragedy included a discussion of the merits of mixed-gender combat units and criticism of the fact that a male and female soldier had been on duty alone at a guard post for an all-night shift. The soldiers served in the mixed-gender light infantry Bardelas and Caracal battalions tasked with guarding the border.
