ISTANBUL (AP) — 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.

Imprisoned Kurdish leader Abdullah Ocalan has called on his militant group to lay down its arms and dissolve as part of a bid to end a four-decade long conflict.
