European and US forces have sent warplanes against Libyan targets under a UN Security Council resolution authorizing military action to protect civilians from leader Muammar Qaddafi’s forces.

Qatar submitted a flight plan for six Mirage jets and one C-130 cargo plane to arrive Monday or Tuesday but it was not clear what their role in Libya would be, said the official, who declined to be named.

“The jets from Qatar are expected at the Souda base in Crete and we will facilitate them if and when they arrive,” he said, adding that Qatar had earlier requested permission for four Mirage jets but changed its request.

The United Arab Emirates had also requested refueling at Souda base for 12 F-16 jets and 12 Mirage jets on their way to Sicily but it was not clear when and if they would arrive, he added.
