DIYARBAKIR: Security forces killed 20 Kurdish militants in southeast Turkey while three Turkish soldiers died in a rebel attack, the military said on Wednesday, as authorities widened a curfew in the mainly Kurdish region’s largest city, Diyarbakir. Hundreds of locals, including children and the elderly, fled curfew-bound areas of Diyarbakir’s Sur district as gunfire and blasts resounded and police helicopters flew overhead, a Reuters witness said. Some people cried as they carried away possessions.
