Pakistan has dismissed as not credible allegations that its troops traded in gold and sold weapons to militias in DR Congo while serving as UN peacekeepers.
A spokesman for the Pakistani military, Maj-Gen Wahid Arshad, told the BBC a UN investigation into the matter was still going on and had not named any country.
The BBC reported on Wednesday that the inquiry into the claims may have been blocked for political reasons.
The UN says it will seek to discipline anyone compromising its operations.
A top commander with the FNI militia, who did not want to be named, has telephoned the BBC to confirm that some of his fellow militia leaders had trafficked gold with UN peacekeepers.
He also said they had been given weapons to fight the rival UPC militia.
Trafficking allegations
On Wednesday, the BBC's Martin Plaut said he had found that the UN had begun an internal investigation in early 2006 into allegations that Pakistani peacekeeping troops had traded in gold and sold weapons to Congolese militia groups they were meant to disarm.
The Pakistani battalion at the centre of the claims was based in and around the mining town of Mongbwalu, in the north-east of the country, two years ago.
They helped bring peace to an area that had previously seen bitter fighting between the Lendu and Hema ethnic groups.
