they spotted some kind of optics following troops. hamas teams frequently have cameramen to film hits or remote controlled cameras in general for surveillance. also sniper rifle reflections and camera optics reflections at large distance looks similiar.
edit: few days ago they identified somebody who put camera on external stairs of hospital near roof and followed troops. troops got attacked a few times. they asked for approval to take whoever it is down. approval was given but it was conditioned to use "light munition" to prevent too much damage. from some reason was used heavier munition. currently they investigate why orders weren't followed.
