It's frontloaded on the Israeli MFA's release about last night's fighting but is way, way below the fold in the AFP blurb:

In a separate incident, a soldier was wounded when Palestinian gunmen opened fire from a mosque which was used "for storing a large amount of explosive substances and explosive devices," the military said in a statement. Another Palestinian militant was killed in an Israeli air strike in the northern Gaza Strip that wounded three other people. The soldiers called in air attacks as the militants fired mortar shells and anti-tank missiles, it said, adding that 10 gunmen were hit.

Reuters doesn't seem to think it's worth mention, but the Associated Press did find some space for it way at the bottom:

Two Palestinian civilians were injured when their house was hit by a tank shell, medics said. The army did not immediately comment. In one of the areas east of Gaza City, Israeli armored vehicles hit and damaged a mosque, local residents said. The Israeli army did not immediately comment on the damage to the mosque.

Yeah. That's exactly what happened.

In all fairness, the updated AP report helpfully added that "the army said" that there were explosives in the mosque. Because what exhibition of media bias would be complete without a demonstration of how to use weasel words when you have to grudgingly concede what you don't want to concede? Say what you will about Ibrahim Barzak's rank anti-Israel bias - you still have to admit that he's definitely getting more subtle.
