It alleged they were “caves, bunkers, shelters, depots and installations” used by the Kurdistan Workers’ Party (PKK), which has fought for Kurdish rights an on-off insurgency against the Turkish state since 1984. It is designated as a terrorist organization by Ankara and its Western allies.
The Turkish army, whose incursions into Iraq are regularly condemned by Baghdad, said it had killed “numerous” militants in its latest assault.
