The underwater search for missing Malaysia Airlines flight MH370 has resumed off the coast of western Australia. One of three ships has arrived in the search area.

The search will use deep-sea video cameras and sonar equipment to scour the seabed.

Australian officials have previously said they are confident the missing plane was flying on autopilot when it disappeared.

The search area in the hunt for the missing jet has shifted several times at suspected crash sites in a remote stretch of Indian Ocean, where a remote underwater drone had been scouring 330 square miles of seabed.

In June, the relatives of missing passengers announced they were seeking to raise some €3.6m to offer as a reward to any "whistleblower" who can offer information leading to the discovery of the lost plane.

It has been six months since the airliner disappeared with 239 people on board on its way to Beijing from Kuala Lumpur.
