Two communities in Solomon Islands have been cut off from the capital Honiara after bridges connecting the areas were destroyed by flash floods.
Solomon Islands Broadcasting reports the flash foods were caused by heavy rain in the mountains.
Chief Bartholomew Vavanga, who is also a former Provincial Assembly member, says the destruction is the second biggest after Cyclone Namu in 1986.
He said the first flash food happened last month and another three followed, isolating communities of Mberande and Mbalasuna.
He fears there may be health problems and food shortages because of the dirty river.
The Guadalcanal Provincial Emergency Operation Centre says an estimated 12-thousand people are affected by the floods.
