The Indonesian navy has released a poignant video showing the crew of a sunken submarine singing on board their vessel.

The video, filmed a few weeks ago, shows the sailors singing an Indonesian hit called Sampai Jumpa (see you later).

Officials confirmed on Sunday that the KRI Nanggala - which sank off the coast of Bali on Wednesday - had been found split into three pieces on the sea bed.

All 53 crew were confirmed as dead.
