US forces kill Iraqi troops in Falluja - doctor

US tanks opened fire on Iraqi security forces in the city of Falluja yesteray, an Iraqi officer said, and Iraqi doctors said two had been killed.

Another eight Iraqis were injured when the tanks fired on a checkpoint in southeast Falluja, the doctors said. A US military spokesman said he had no information on the incident.

US forces pulled out of Falluja in early May after weeks of fighting that killed hundreds of Iraqis and aroused nationwide outrage. Security was handed over to an Iraqi force which has since largely disintegrated.
