There are witness statements from people who were involved in Akber Bugti saga. He was ratted out by tracking his Thuraya mobile signal. Once he was pin pointed,he was told that a delegation will come to talk to him and that was biggest mistake in the whole of the operation.
On the agreed date and time and Army delegation landed near the cave he was staying.As soon as the delegation went in the whole cave exploded as it was pre-laced with explosives. The blame was thrown on Pakistan army for killing Bugti and thats how BLA and all other insurgency business started. No better business than dirty politics and to run it you need a "Shaheed" to woo the Jazbatii people of Pakistan and killing Bugti this way,worked perfectly for the little Bugtis who are still feasting on the spoils of their perfect plan to kill their own grand dad.
