A US unmanned plane crashed near the western Iraqi town of Qaim bordering Syria as clashes ravaged the restive Anbar province, medical sources said on Thursday.

"A drone crashed as clashes erupted in the town between insurgents and the US troops that left three people dead and two others wounded," Muhammed Salih al-Iysawi, a doctor in Qaim hospital told Xinhua.

Iysawi did not specify the reason of the crash.

The US military did not confirm the information from the Qaim town.

In Ramadi, some 110 km west of Baghdad, several mortar rounds landed on an area where the hospital of Ramadi stands, wounding five people and destroying a US Humvee, witnesses said.

Iraq's Anbar province, where Ramadi, Fallujah and Qaim locate, has long been a hotbed of insurgency against the US troops and Iraq's fledgling security forces.
