"Negotiations are over, and we are waiting for orders" to attack, said Mohammed al-Fassi, a rebel commander at a staging area about 45 miles from Bani Walid. "We wanted to do this without bloodshed, but they took advantage of our timeline to protect themselves."Libyan rebels are poised to attack one of Moammar Kadafi's remaining strongholds, but their military spokesman said Sunday he expected the town's tribal leaders to surrender rather than see their divided followers fight one another.
