ISTANBUL (Reuters) - The advance of Sunni militants in Iraq leaves Turkey facing a widening Islamist insurgency in two of its southern neighbours, endangering domestic security, threatening important trade routes and forcing it again to rethink Middle Eastern policies.
Militants from the Islamic State in Iraq and the Levant (ISIL) overran the northern Iraqi city of Mosul, 110 km (68 miles) from the Turkish border, earlier this week and have since thrust southwards towards Baghdad, seat of the Shi'ite Muslim-led central government.
