In Libya the so-called Islamic State group is battling to hold on to its stronghold of Sirte after forces aligned with the new unity government advanced on the city.<br /><br /> Security sources said they made ground in the eastern and southern outskirts, taking control of at least one military camp. This hasn’t been confirmed.<br /><br /> A hospital spokesman said at least six brigade members had been killed and 30 wounded in the clashes.<br /><br /> The units launched a counter-offensive against ISIL last month from their base in the western city of Misrata, pushing the militants back along the coastal road to Sirte.<br /><br /> They are allied to the UN-backed Government of National Accord which has been trying to stamp its authority on Libya’s various fractious groups.<br /><br /> The country sunk into chaos after its veteran ruler Muammar Gaddafi was toppled five years ago. ISIL moved in to set up its most important base outside Iraq and Syria.<br />
