Pentagon: no comment on report of troops in N.Iraq

Al-Jazeera quoted Turkish military sources as saying 50 U.S. military trucks had started transporting equipment on Saturday from an air base in southern Turkey into three areas in northern Iraq controlled by Kurds. The report said the trucks had used the Habur border crossing.

"Jazeera learned that there are 500 U.S. special forces training around 2,000 Kurds and making logistical preparations for the arrival of thousands of U.S. troops in the event of an attack on Iraq," the Qatar-based television channel said.

The Turkish military rarely if ever provides information to foreign media.

The Turkish broadcaster NTV also aired a report on Sunday saying 50 U.S. military vehicles had crossed into Iraq through Habur and that the number of "American intelligence and military personnel in northern Iraq has reached 500".

NTV did not give a source for the story.

Washington would look to Turkey for the use of air bases in any military operation against neighbouring Iraq over Baghdad’s alleged possession of weapons of mass destruction.

The United States already uses Turkish air bases to patrol a so-called "no-fly" zone over northern Iraq that U.S. and British planes have enforced since the end of the Gulf War.
