For government forces, this is the first time they are setting foot in PK5 since 2014.
The United Nations and government forces in the Central African Republic (CAR) have declared a notorious neighbourhood in the capital Bangui a weapons-free zone.
The area, known as PK5, recently saw days of fighting between a militia and local traders.
The armed group was given a deadline to disarm, which has now passed.
