Two pieces of aircraft debris found on beaches in Mauritius and South Africa almost certainly came from Malaysia Airlines flight MH370, say Malaysian and Australian officials.
It is the latest development in efforts to solve the mystery of the aircraft, which went missing in March 2014.
The plane, flying from Kuala Lumpur to Beijing, had 239 people on board when it vanished.
It is presumed to have crashed into the sea after veering off course.
Three ships are searching a 120,000 sq km area of the southern Indian Ocean but have so far found no trace of the plane.
Five pieces of debris have been confirmed as definitely or probably from the plane.
Each was found thousands of miles from the search zone, though within the area models of ocean currents have indicated debris could wash up.
