Libyan forces said they had advanced against some of the last holdouts of the self-styled Islamic State terrorist group in Sirte on Saturday, as fighting resumed after several days of relative calm. The forces, which are aligned with Libya’s UN-backed government, launched their campaign to recapture the city in May and have been aided by dozens of US airstrikes since the beginning of August. Forces now say they are in the final stages of their campaign to oust IS from its former North African stronghold, Reuters reported.
