MH370 search uncovers shipwreck

Authorities searching for the missing flight MH370 have discovered a 19th century shipwreck at the bottom of the southern Indian Ocean.

The steel or iron vessel was discovered after sonar scanning identified an object resting on the ocean floor on December 19.

An unmanned underwater vehicle captured high-resolution sonar images of the wreck on January 2.

The 120,000 square kilometre search area, expected to be completed by the middle of this year, will not be expanded if no credible information as to the location of the aircraft is uncovered.
