The historical district of Sur in Diyarbakir has been under curfew since December 11 last year.
The infrastructure has been largely destroyed by shelling. An estimated 200 people are still trapped in the basements, including 15 children under 10 years of age and an unknown number of wounded people. Civilians cannot leave their homes due to the continuous shelling and dead bodies are lying on the streets.
The Turkish authorities acknowledge the presence of 131 civilians and 25 PKK militants.
