"I urge the PCJSS to co-operate with the government," he said. "People here are now living in peace and harmony with development of the region going on in full swing."

The minister said much of the accord had already been implemented, including the closure of many military camps, the release of some jailed tribal rebels and the induction of hundreds of former insurgents into the local police force.
