Floods block food from reaching thousands of refugees in Colombia

Families fleeing drug gangs and paramilitaries have been cut off, with government accused of being incapable' of protecting them

Flooding and landslides have left thousands of refugees cut off from food supplies in Ituango, the conflict-strewn municipality in north-western Colombia.

Roads have been blocked by mud and debris after heavy rains, while helicopters have been unable to land. As a result, the delivery of food and medical supplies has been stymied, and communications cut off.
