Turkey’s interior minister says six Islamic State militants and three police officers were killed in a clash in northwest Turkey. The shooting occurred in Yalova province, south of Istanbul, on Monday. Police stormed a house where the militants were hiding. Eight other police officers and a night guard were wounded, according to Interior Minister Ali Yerlikaya. Special forces from neighboring Bursa province were dispatched to reinforce the operation. Authorities cut off natural gas and electricity supplies as a precaution. Last week, police detained 115 militants allegedly planning attacks targeting Christmas and New Year’s celebrations.
