Search efforts are expected to intensify as a Mauritius based company, Deep Ocean is expected to join search teams within a week.

Investigators have been searching the flight recorders in the deepest waters .

Experts say flight recorders are able to emit acoustic signals 30 days after a crash and can be spotted in waters which are about 3000 metres deep.

Finding the black box will help investigators to determine whether the EgyptAir crash was caused by a technical fault or a terrorist attack.

The EgyptAir crashed on May 19 with 66 passengers on board while flying from Paris to Cairo.

Before the crash, the plane had vanished from radar screens.
