With the number of people fleeing the crisis in Syria showing no signs of stopping, the UN refugee agency (UNHCR) says overcrowding at refugee camps in neighbouring countries is increasing.

It says overcrowding also putting a heavy burden on sanitation and contributing to disease outbreaks and tension between camp residents.
