New Caledonia calamity described as worst since 19th century

New Caledonia's president Philippe Germain has described this week's fatal landslides and flooding as a catastrophe not seen since the 19th century.

So far five bodies have been recovered in two settlements near Houailou on the main island's east coast where about 400 millimetres of rain fell in 12 hours.

Three people are still missing and eight others have been injured.

The villages of Gouareu and Ouakaya were hit by the landslides which came off a mountain range which the mayor of Houailou Pascal Sawa said had been weakened by nickel mining and bush fires.

The area was considered to be at risk after major slips in 2008 and 2011.

The affected zone is on customary land where building permits aren't needed

Mr Germain said damage assessments are continuing and extraordinary assistance will be made available.
