A Turkish Airlines flight en route to Brazil was forced to change course and land in Casablanca after a bomb threat, a spokeswoman said on Monday.

Flight TK15 had departed from Istanbul and was headed for Sao Paulo with around 250 passengers on board when it declared an emergency and diverted to the North African city, the spokeswoman said.

The Boeing 777 landed in Casablanca by around 1230 GMT.

No further information was immediately available.
