For one elderly man who arrived in Dera Ismail Khan this week from the Ladha area of South Waziristan, this is the fourth time he has had to flee his home because of fighting between the army and the Taliban.
Most of these troops belong to the Tutsi racial group and their dismissal led many fellow Tutsis from Congo known as Banyamulenge to move out of western and central Congo and flee to their home country in the east.
