The Jordanian flag carrier Royal Jordanian has suspended its daily flights to Baghdad after being told by the US military that it could not land there on safety grounds, a company official said on Tuesday.

"US military authorities told RJ that there was no clearance on safety grounds until further notice," the official said. The airline had suspended its two daily flights to Baghdad on Sunday, he added.

Iraqi insurgents often fire mortar bombs at the airport.

"As soon as there is clearance, RJ will resume its flights," the official said.

Royal Jordanian was the first commercial airline to resume flights to Baghdad after the US-led invasion of Iraq in March 2003.
