Heavy rains have collapsed sections of a highway in southwestern Uganda linking it to Rwanda, slowing goods transport between the two landlocked countries, a roads official said on Thursday.

The East African country has received unusually heavy rain since December, leading to a wave of devastating landslides in mountainous regions and damaging farms and transport infrastructure.

Heavy rains in eastern Uganda triggered a massive landslide last week that killed over 80 people after burying three hamlets in the Bududa district. Landslides have also occurred in the country’s southwest and western regions, causing limited damage.
