Turkish jets launched air strikes on a Kurdish militant camp in northern Iraq late on Tuesday, September 22, targeting a facility being used as an "education and logistics" hub, security sources said, according to Reuters.

The jets took off from an air base in Diyarbakir, southeast Turkey, the sources added. Turkish security forces have regularly targeted camps belonging to the outlawed Kurdistan Workers' Party (PKK) since the collapse of a ceasefire in July.

The PKK began its separatist insurgency in 1984, triggering a conflict that has killed more than 40,000 people. The group, which says it is now fighting for greater Kurdish autonomy, is designated a terrorist organization by Turkey, the European Union and the United States.

President Tayyip Erdogan has promised the fight will go on until "not one terrorist is left". The conflict has flared up as Turkey prepares for a parliamentary election on Nov. 1 following an inconclusive June vote.
