April 2017 Turkish airstrikes in Syria and Iraq

The attacks were authorized by the General Staff of the Republic of Turkey, who stated that the bombings targeted the Kurdistan Workers' Party (PKK) and were attempts to prevent the PKK from "sending terrorists, arms, ammunition and explosives" to Turkey.[1] At around 2 a.m. EEST, Turkish planes conducted several airstrikes on YPG and YPJ positions atop Mount Qarachok, near the town of al-Malikiyah. The targets of the airstrikes were a YPG media center, a radio station, a telecommunications facility, and military bases. The airstrikes killed 12 YPJ and 8 YPG fighters and injured 18 more.[2][5]

At around 2:30 a.m., Turkish airstrikes hit reported PKK positions atop Mount Sinjar. The airstrikes hit a Peshmerga communications tower and killed 5 Peshmerga soldiers and injured 9 more.[6] Per the mayor of Sinjar city, no casualties were reported among the PKK.[7]

Recep Tayyip Erdoğan, the President of Turkey, stated that "We are obliged to take measures. We must take steps" after the airstrikes. Turkey stated to have contacted the United States, Russia, and Masoud Barzani, President of Iraqi Kurdistan, prior to the attacks. In response to the airstrike on a Peshmerga position which killed 5 of their soldiers, Erdoğan stated that it was "absolutely not an operation against [them]."[8]
