Brazilian Air Force aircraft have detected larger items of debris in their search for the presumed crash location of the missing Air France Airbus A330.
In an update the Brazilian defence ministry says the air force's Embraer R-99 has identified four areas of wreckage about 90km south of the original region being covered by the search aircraft.
The observations included a section debris around 7m (23ft) in diameter, an oil trace stretching to some 20km, and various other objects, including pieces of metal.
Eleven aircraft, operating from Natal and Fernando de Noronha, are being used in the search, among them a US Lockheed P-3 which has recently joined the effort.
The P-3 and four other aircraft - three Lockheed C-130s and a Dassault Falcon 50 - are conducting flights to verify the R-99 crew's sightings.
Scrutiny of the ocean surface has concentrated on a region some 700km northeast of Fernando de Noronha.
Five Brazilian naval vessels are en route to the search area, while three Dutch and French merchant ships have already arrived to aid recovery.
