AlQa'dah 25, 1433, Oct 11, 2012, SPA -- At least three people were killed when Libyan troops shelled a former stronghold of the late Libyan president, dpa cited local media as reporting on Thursday. Libyan troops have been besieging Bani Walid, some 400 kilometres south-east of the capital Tripoli, for more than a week in an attempt to catch suspected rogue militiamen. Libya's new rulers have recently ordered illegal militias to be disbanded and launched a disarmament drive in an effort to re-establish security in the northern African country.
