ISIL threat prompts curfew in Iraq's Kirkuk

Iraqi security forces have imposed a curfew on the oil rich city of Kirkuk to prevent ISIL-led militants from provoking trouble, police sources said.  The curfew came into force at 11 p.m. local time (GMT 20:00) on Tuesday after unidentified people, believed to be ISIL supporters carrying Kurdish Regional Government's flags, attempted to stir up trouble, according to information the Anadolu Agency received from security sources. Kirkuk, 80 kilometers south of the Kurdish regional capital of Erbil, has been under the control of Kurdish forces, known as peshmerga, since the Iraqi army fled the city in the face of a major ISIL-led offensive in early June. The road between Kirkuk and Erbil is considered the region's lifeblood with its busy traffic of lorries carrying crude oil across the border with Turkey and Iran. Over the last month, the Kurdish government has deployed thousands of peshmerga along the city's southern border to prevent a new northern advance by ISIL forces, which hold a strong presence in cities and towns south of Kirkuk. Meanwhile in Iraq's second city, Mosul, clashes between peshmerga fighters and ISIL have left eight people including five militants dead, according to security sources.

Fighting in Mosul between Kurdish and ISIL forces intensified last week when ISIL-led militants seized control of several towns in the area and began to threaten the country's largest hydroelectric dam, known as the Mosul Dam.

The towns recently captured by ISIL include Sinjar, which is the ancestral home of the Yazidi religious minority. Yazidi is an eclectic religious sect fusing Zoroastrian, Manichaean, Jewish, Nestorian Christian and Islamic elements. It is regarded as heretical by orthodox Islamic scholars.

As many as 500 Yazidis have been killed by Islamist militants since they seized control of the town Sunday, forcing at least 30,000 families to flee to the cities of Erbil and Duhok in the north, according to Yazidi officials.

Tension continued to remain high in Iraq after the ISIL-led militants, also backed by tribal fighters, seized Mosul on June 10 and captured a number of other cities in the north, including Tikrit and Tal Afar.
