The Philippines has declared a state of national calamity after last week’s flash floods and landslides.

More than 1,000 people are said to have died and tens of thousands more made homeless. The national disaster has also sparked a health crisis over the treatment of the dead to prevent disease from spreading.

Most of the casualties have been in the cities of Cagayan de Oro and Iligan in the Mindanao region.

The disaster agency says more than 338,000 people in 13 provinces have been affected by typhoon Washi, with nearly 43,000 others still in evacuation centres.
