At least two cars driven by suicide bombers exploded Monday at the entrance to a U.S. military camp in western Iraq.

Early reports from the camp near Qaim say at least two U.S. personnel were wounded in the attack. A military spokesman in Baghdad said officials were still gathering details early this afternoon.

Meanwhile, Iraqi security forces backed by U.S. troops rounded up dozens of suspected insurgents during raids today in central Baghdad.

A U.S. military statement says more than 500 Iraqi soldiers and police took part in the operation.

In other developments, Pakistan says kidnappers are seeking ransom for the release of an embassy employee abducted Saturday in Baghdad.

A Pakistani Foreign Ministry spokesman declined to disclose details, but he said the victim, Malik Mohammed Javed, is unharmed and in contact with embassy officials.
