DIYARBAKIR, Dhu-AlQa'dah 22, 1436, September 06, 2015, SPA -- Two policemen were killed and three others injured in predominantly Kurdish eastern Turkey's largest city when Kurdish militants clashed with security forces early on Sunday, government sources said, according to Reuters. Gunfire and explosions echoed across the centre of Diyarbakir on Sunday morning after fighters from the outlawed Kurdistan Workers' Party (PKK) fired a rocket-propelled grenade at police trying to fill in ditches dug by the PKK in the Sur district of the city. Security forces responded with an air-supported operation against the militants and the governor's office imposed a curfew in the area, ordering all residents to remain indoors. --SPA 14:36 LOCAL TIME 11:36 GMT www.spa.gov.sa/w
