Much of the division in this fighting was largely along clan lines; the BIG/BRA was dominated by the Nasioi clan, causing other islanders to view it with suspicion. On the island of Buka north of Bougainville, a local militia formed and drove out the BRA with the help of Papuan troops, during a bloody offensive in September 1990. Multiple agreements were signed but were not honoured by any parties. The BRA leadership of Ona and Kauona fell out with some of the political leaders, such as Kabui. Several other village militias, which together became known as the resistance and were armed by the PNG defence forces, forced the BRA out of their areas.
