A bomb exploded on Saturday in Arbil, the capital of Iraq's Kurdistan region, a relatively stable region which has recently come under threat from advancing Islamic State militants, local television network Rudaw reported. TV footage from the scene showed firefighters dousing the charred remains of a car, which blew up outside a technical college on the road from Arbil to Kirkuk. Kurdish security forces have been on high alert since Islamic State militants overran large swathes of Iraq, opening a more than 1,000 km-long (600-mile) front with the semi-autonomous region. The last major attack in Arbil was in September, when militants launched a coordinated suicide and car bomb attack on the headquarters of the security services.
By Heba al-Shibani and Ayman al-Warfalli TRIPOLI/BENGHAZI Libya (Reuters) - The air force of Libya's renegade general Khalifa Haftar on Saturday attacked positions of Islamist-leaning militia in Tripoli for the second time in less than a week, one of his commanders said. The faction under attack, Operation Dawn mainly from the town of Misrata, said the raids had killed 10 people and wounded dozens. Haftar launched a campaign against Islamists in the eastern city of Benghazi in May. He threw his weight behind fighters from the western region of Zintan who are battling militia from the town of Misrata, east of Tripoli. In the 2011 NATO-backed campaign to oust Muammar Gaddafi fighters from Zintan and Misrata were comrades-in-arms but they later fell out and this year they have turned parts of Tripoli into a battlefield.
