Outlawed Kurdish group the PKK has declared a ceasefire with Turkey after its jailed leader Abdullah Ocalan called on the movement to lay down its arms and dissolve itself.

The outlawed Kurdistan Workers Party (PKK) militant group declared an immediate ceasefire on Saturday, a news agency close to it said, heeding jailed leader Abdullah Ocalan's disarmament call, in a major step toward ending a 40-year insurgency against the Turkish state.

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.
