Images of Congolese refugees displaced by fighting in eastern Congo at the Bukanga transit camp in Uganda, which is worried that the rising stream of refugees could give easy passage for rebels to launch attacks in the country.

The Uganda Red Cross Society said 66,000 Congolese refugees have so far crossed into the east African country since the Allied Democratic Forces (ADF) started attacking the eastern Democratic Republic of Congo town of Kamangu on Thursday.

Paddy Ankunda, Uganda's military spokesman, said the large Congolese influx had negative security implications in the country's western region should rebels sneak in as refugees.

"You can’t be sure of the identity of each and every individual refugee and also the increasing volatility of the security situation right across the border worries us. Kamangu is only about 10 km (six miles) from the border," he said.
