Flushing out IS fighters in Libya's Sirte

The Libyan forces are preparing for what they hope to be the last attack against so-called Islamic State (IS) group in the city of Sirte.

IS fighters were surrounded in two districts, but the government forces postponed the operation to allow hundreds of civilians, thought to be held under IS control, a safe passage to leave.

BBC Feras Kilani has this exclusive from the front line there; he was told that the attack should start Saturday morning.
