As regards the mosques, by contrast, Israel's declaration that it is firing on them because they are hubs of Hamas terrorism has met with no emphatic denials, no aggrieved assertions from Hamas clerics that their buildings are innocent places of humble worship, no pleas to the international community to enter the buildings and document their purity.

Britain's Observer newspaper reported last Sunday, after the IAF struck the Ibrahim al-Maqadma mosque in northern Gaza's Beit Lahiya, that Al-Jazeera's Gaza correspondent, Ayman Mohyeldin, believed the attacks "could galvanize the Arab world into taking action against Israel." But this doubtless objective correspondent's professional assessment did not prove prophetic.

The name of that mosque rather gives the game away, of course. Maqadma was one of the founders of Hamas and its military chief. He was killed in an Israeli helicopter strike in Gaza in March 2003, soon after a series of Hamas terror attacks, including a suicide bombing on an Egged bus in Haifa that killed 17 people.

Israeli security officials say the mosques that have been struck, long known as centers of Islamist indoctrination and vicious anti-Israeli and anti-Jewish incitement, are being used as weapons stores, command centers, as cover for networks of tunnels - in short, Hamas military positions. Again, there has been no frenzied rush by Gaza's clerics to dispute this devastating accusation.

"We did not easily take the decision to hit mosques," an Israeli security official said this week. But one of those targeted was the entry point to a whole series of tunnels, he said. Another was a storehouse for Grad missiles fired into Israel. (On Wednesday, the IDF released footage of a rocket being launched into Israel from immediately adjacent to the wall of a mosque.) "When you see, day after day, people going back into a mosque for their rocket supplies," the official said, "you have to act."

Along with the absent protestations of innocence, however, there is also a regrettable absence of internal Islamic condemnation of the abuse by Hamas of its holy places.
