Air France jet turned back by US

An Air France jet was diverted from Boston in May

US authorities have ordered an Air France flight from Paris to Chicago to turn around after only two hours in the air after concerns about a passenger.

"After the plane had left the Americans reacted and said that one of the passengers had a name that was on their list," French police said.

Flight AF050 landed at Charles de Gaulle airport at 1915 (1715 GMT) on Friday, four hours after taking off.

The passenger in question and four others were taken for checks.

There was no information given on the names of the passengers, their age or nationalities.

Air France said the flight would take off again in the evening, after the plane had been checked over.

French police said flights from France to Britain and the United States were being treated with extra caution following Thursday's bomb attacks in London, AFP reported.

In May flights from Italy and France to Boston were diverted because of fears about passengers on board.

In September last year a flight carrying the singer Cat Stevens to the US was diverted because the name he adopted when he became a Muslim, Yusuf Islam, was on the US no-fly list.
