Second Libyan Civil War
The Islamic State of Iraq and the Levant's branch in Libya (Libya Province) seizes control of the western Libyan town of Sabratha, after storming it in retaliation after two of their men were arrested in a house nearby; however they then set up checkpoints around the town, with little opposition from the local militias that were supposed to be in control of the area. There are now fears that the militant group could destroy the town's Roman amphitheatre, which is a UNESCO World Heritage Site.
