The Marines are going at it in Fallujah:

The firefight, though, continued for a good two hours after that. [There were] very heavy exchanges of gunfire; U.S. Marine Cobra attack helicopters were called in.

They were firing off missiles, and also we're told a mortar platoon from further back in the rear was firing off 8-millimeter mortars, and those impacted in a number of buildings behind us, setting them on fire and sending plumes of black smoke into the air.

Also, there was a mosque ... here; it had a minaret 50 to 60 feet high. Marine commanders say they were taking sniper fire from that minaret.
That minaret has now been leveled by U.S. military ordnance, missiles and mortars. There's nothing left at all of that minaret. ...

Emphasis mine. Mosques cease to be mosques when used for military purposes, they then become targets and should be treated as such.
