A Turkish airstrike on a police training center in northeast Syria resulted in 20 deaths and dozens of injuries, targeting Kurdish security personnel. The strikes are part of a broader retaliation by Turkey for an attack in Ankara earlier this month, claimed by a branch of the Kurdistan Workers’ Party (PKK). Turkey has been conducting air raids since Thursday, hitting civilian and military targets. The Kurdish-led Syrian Democratic Forces (SDF), which Turkey views as an offshoot of the PKK, denied any connection to the attackers in Ankara. Tensions persist between Turkey and Syrian Kurds, complicating the complex Syrian conflict.
