It has been confirmed that orange objects floating in the water, suspected to be life vests from the missing Malaysia Airlines jet, are nothing more than dead jellyfish.

It comes as Chinese relatives are staging a protest in Kuala Lumpur today - demanding answers from the Malaysian authorities.

It is the busiest day of the air and sea search so far with hopes the flight recorder may be located.

Ten aircraft and eight ships have joined the search for the missing plane in the Indian Ocean and one of the vessels has been fitted with a special black box detector.

The flight recorder's batteries are due to run out in a matter of days and therefore it is crucial they find the black box soon.

It has been 22 days since the aircraft disappeared.
