Five Japanese scuba divers were found alive this morning in waters off the Indonesian resort island of Bali three days after going missing, police said.

Two others who were with them are still missing.

A huge search swung into action after the seven women went missing on Friday during their third dive of the day from the island of Nusa Lembongan, just east of Bali.

Rescue efforts were hampered by poor weather, with a helicopter only able to join the search in the afternoon.

But four of the women were found alive in waters 300m off the coast of Nusa Penida, an island just southeast of Bali, said local police chief Nyoman Suarsika.

He did not have news of the three women still missing, and could not immediately say exactly where the other four were rescued or give their names.
