Australia's Deputy Prime Minister has said his government remains "very confident" that missing flight MH370 is in a particular part of the southern Indian Ocean
The search for the Malaysia Airlines plane was narrowed last month after a series of acoustic pings thought to be from the plane's black box recorder were heard in an area around 1,000 miles from Australia's north-west coast.
Warren Truss told the Australian parliament: ""We are still very confident that the resting place of the aircraft is in the southern (Indian) Ocean, and along the seventh ping line" - a reference to an arc identified by analysis of satellite communications data.
