FALLUJAH, Iraq (AP) - U.S. forces cornered insurgents Wednesday in a narrow strip of Fallujah after a stunningly swift advance that seized control of 70 percent of the militant stronghold. An Iraqi general said troops found "hostage slaughterhouses" where foreign captives had been killed.

The abandoned houses had hostages' documents, CDs showing captives being killed, and black clothing worn by militants in videos, Maj. Gen. Abdul Qader Mohammed Jassem Mohan said...

...The speed of the U.S. drive in Fallujah may indicate that most Sunni fighters and their leaders abandoned the city before the offensive and moved elsewhere to carry on the fight, officers said. The most notorious kidnapper, Abu Musab al-Zarqawi, is believed to have fled the city.

Many of the remaining fighters have asked to surrender, government spokesman Thair al-Naqeeb told reporters. He said Iraqi authorities "will extend amnesty" to those who have not committed major crimes...

...10 U.S. troops and two members of the Iraqi security forces had been killed. Marine reports Wednesday said 25 American troops and 16 Iraqi soldiers were wounded.
