One area was under forced curfew for nine days, and several died as a result of lack of access to food, water, and medicine.
Hundreds of militants and members of the security forces have died since hostilities resumed between the PKK and the state after the collapse of a ceasefire in July, shattering a peace process launched in 2012 to end a three-decade conflict.
The government resumed air strikes against the PKK two months ago in response to what it described as a sharp escalation in attacks on the security forces and shootings in urban centers. President Tayyip Erdogan has promised the fight will go on until "not one terrorist is left".
