Islamic State of Iraq and Syria (ISIS) group has claimed a suicide car bombing at a checkpoint near Libya's western Misrata city on Thursday after the jihadist militants took over former dictator Muammar Qaddafi's home city of Sirte. State news agency LANA quoted a military source as saying that the suicide car bomber blew himself up at the checkpoint on Thursday, killing two guards. The attack, claimed by ISIS, targeted forces from the port city whose troops are allied with a self-declared government controlling the capital Tripoli and western Libya. Misrata forces had fought with ISIS on Wednesday in Sirte. At least one person was killed and seven wounded. ISIS forces have profited from Libya's turmoil, four years after the overthrow of Muammar Qaddafi, to gain a foothold in the north African country while two rival governments battle for power and Libya's oil wealth. Thursday's attack "led to the killing and wounding of the enemies of God," ISIS said in a message on Twitter. A Reuters reporter saw several damaged cars at the checkpoint on the road east of Misrata towards Sirte, a central city seized by ISIS in recent months.
