Monsoon rains in Sri Lanka have killed eight people, with 172 more people requiring rescue by the armed forces. Eight districts have been affected as up to 150mm of rain fell across the country.

Adverse weather conditions have closed roads and displaced many people prompting the government to deploy members of the army to provide emergency evacuation and relief efforts. Power supplies have been interrupted in many areas across the country as flood waters and falling trees took down power lines.

As the heavy rain continued, landslide warnings have been issued across several districts while 'red alert' flood warnings were issued to people in four districts living alongside major rivers.
