U.S. jets drop 500 lb bombs in Iraq operation

"BAGHDAD (Reuters) - U.S. F-16 fighter planes dropped a series of 500 lb (220 kg) bombs on insurgent targets in western Iraq overnight as the U.S. military launched a heavy offensive against rebels near the Syrian border.

Nine of the powerful bombs were dropped, the U.S. military said, two of them targeting suspected rebel safe houses near the town of Qaim, an insurgent stronghold on the Euphrates river about 20 km (12 miles) east of Iraq's border with Syria.

Four more were aimed at rebels as they fired mortars and assault rifles at U.S. ground forces near Qaim, and a further three were used to hit suspected weapons caches in the area."

This almost sounds like they must have had some intelligence on the ground, Where did that come from?
Something tells me that the regular Iraqis are tiered of the help they are receiving from thier brothers in arms, the glorious foreign resistance, and have decided that if there is going to be a resistance, it has to be Iraqi.
