The search for the main wreckage of AirAsia QZ8501 in the Java Sea has entered a second week, with poor weather still hampering operations, BBC News reports.

Divers had hoped for better conditions but faced continued suspensions. A fifth large object, thought to be debris from the plane, has been located under the sea. Another body has also been found, bringing the total to 31.

Flight QZ8501 crashed en route from Surabaya in Indonesia to Singapore last Sunday, Dec 27 with 162 people aboard.

Bad weather is believed to be the biggest factor in the crash. The Airbus A320's "black boxes", or flight data recorders, have yet to be located. Most of the victims' bodies are thought to be trapped in the plane's fuselage.
