Charter plane with Americans aboard forced to land in Iran, then flies to Dubai

(CNN) -- A charter airplane carrying military contractors, including Americans, took off early Saturday from Iran, hours after its pilots were ordered to land because the flight plan was out of date, a U.S. State Department spokeswoman said.

The Fly Dubai charter landed in Dubai a short time later, spokeswoman Marie Harf said.

The news brought to an end an incident that began late Friday when the charter plane en route to the United Arab Emirates was told by Iran that it needed to return to Afghanistan, a number of U.S. officials said.
