'Low risk' of chemical attack.
Serbia inherited part of a chemical warfare programme being developed in the former Yugoslavia, Mr Robertson disclosed in a Commons written reply.
He told MPs: "The former Yugoslavia did have an offensive chemical warfare programme, which included small stocks of chemical weapons.
"Serbia inherited some elements of this in 1992, but the exact status of this programme is unknown."
The Defence Secretary declared: "It is assessed that the current threat to our forces from chemical warfare is low."
