According to this:

The U.S. military said on Sunday it had captured or killed fighters from Sudan, Egypt and other countries in Iraq, and some of those captured had led it to a terrorist training camp.

Brig. Gen. Vincent Brooks told a briefing at Central Command in Qatar that the camp, found at Salman Pak southeast of Baghdad, demonstrated "a linkage between this regime and terrorism." But he said there was nothing to tie the camp to specific organizations.

Someone must be a bit confused, because Salman Pak has been known about for a long time.
