A court has convicted five people of manslaughter over the deadly 2012 Costa Concordia shipwreck off Italy, BBC News reported.

The boat's helmsman, on-board hotel director, two naval officers and the head of the Italian cruise company's crisis unit will be sentenced later.

Thirty-two people were killed when the Costa Crociere ship capsized off the island of Giglio in January 2012.

The trial of Captain Francesco Schettino has been adjourned after he requested electrical tests on the ship.

He is charged with multiple manslaughter for causing the shipwreck and abandoning the vessel with thousands still aboard. His case will resume on 23 September after Italy's summer holidays.
