At least Seven Libyan soldiers were killed repelling an attack on their post by Islamist militants eight km (five miles) southwest of the eastern city of Benghazi on Monday, a military source told Reuters. The troops belonged to the Libyan National Army (LNA), which supports the internationally recognised government, and were trying to prevent fighters loyal to Islamic State capturing tanks in the town of Annawaghia. Benghazi is one front in Libya's complex conflict involving two rival governments, their allied armed factions, and Islamist militants who have gained a foothold in the chaos that prevails four years after the fall of Muammar Gaddafi.
