The mountains of northern Iraq have for years been a sanctuary for Kurdish militants fighting a decades-long insurgency against the government in neighboring Turkey.

Kurdish militants who have waged a 40-year insurgency in Turkey declared a ceasefire on Saturday in what could mark a significant boost to President Recep Tayyip Erdogan's government, two days after their imprisoned leader called for the group to disarm.

The Kurdistan Workers Party (PKK) militia on Saturday declared an immediate ceasefire, two days after its jailed leader Abdullah Ocalan called on fighters to lay down their arms and dissolve the group.
