The Turkish air force carried out a series of airstrikes on Kurdish rebels in Syria and Iraq on April 25, highlighting Turkey's intent to continue weakening the Kurdish forces it opposes beyond its borders — despite last month's formal end of its offensive in Syria, named Operation Euphrates Shield . In Syria, the Turks targeted a Kurdish People's Protection Units (YPG) headquarters on Mount Karachok, near the Iraqi border. The Turkish air force also struck what Ankara claims were positions held by the Kurdistan Workers' Party (PKK) — a Turkey-based Kurdish militant group with links to the YPG — in the volatile Sinjar region of Iraq. In recent months, Turkey has repeatedly denounced what it claims is a growing PKK presence in Sinjar and has vowed to dislodge the rebels from the area. The strikes were Turkey's first in Sinjar.
