DIYARBAKIR, Turkey, Dhu-AlQa'dah 29, 1436, September 13, 2015, SPA -- Kurdish militants on Sunday killed two police officers when they bombed a checkpoint in Sirnak in southeast Turkey and a curfew was imposed in central Diyarbakir, the region's largest city, after clashes there, security sources and officials said, according to Reuters. The carbomb at a police checkpoint in Sirnak province also wounded five other officers and was followed by clashes nearby in which Turkish security forces killed five Kurdistan Workers Party (PKK) fighters. More than 100 police and soldiers have been killed, along with hundreds of militants, since a ceasefire collapsed in July, shattering a peace process launched in 2012. It is the worst violence Turkey has seen in two decades. In Diyarbakir, the historic Sur district was put under curfew and seven police officers were wounded in clashes with militants there, the governor's office said. --SPA 13:58 LOCAL TIME 10:58 GMT www.spa.gov.sa/w
