It is among the countries most vulnerable to disasters and climate change, according to the Global Climate Risk Index.

A bulletin from the disaster ministry on Friday said: “4.5 million people have been affected, and 13 people have died across the country”.

Nearly 190,000 others were taken to emergency relief shelters, according to the bulletin.
