A bomb explodes at Istanbul's Sabiha Gökçen Airport, killing one airport cleaner. The Kurdistan Freedom Hawks claim responsibility for the attack four days later.

The Sabiha Gökçen Airport bombing took place on 23 December 2015 in the apron area of Sabiha Gökçen International Airport in Istanbul, Turkey. The explosion, which occurred at approximately 02:05 local time, wounded two airport cleaners, one of whom later died after being taken to hospital. Flights from the terminal resumed as normal while Binali Yıldırım, the Minister of Transport, Maritime and Communication, claimed that there had been no security lapses at the airport. Witnesses initially claimed that they heard three successive blasts, though their cause was unknown and investigators refused to rule out terrorism as a motive. The Daily Telegraph claimed that the blast was most likely caused by a bomb.

Istanbul Sabiha Gökçen International Airport is the secondary international airport serving Istanbul, Turkey. Located 32 km (20 mi) southeast of the city centre, Sabiha Gökçen Airport is in the Asian part of the transcontinental city and serves as the operating base for AJet and Pegasus Airlines.

The Kurdistan Freedom Hawks, or TAK, is a Kurdish nationalist militant group in Turkey seeking an independent Kurdish state in Turkish Kurdistan. The group also opposes the Turkish government's policies towards Kurds in Turkey. It has been designated as a terrorist organization by the US, UK and Australian governments.
