Turkish authorities believe the person who carried out a bomb attack in Istanbul on Sunday is linked to Kurdish militants but they are not ruling out Islamic State ties, a senior Turkish official said.
The official told Reuters that initial findings pointed to the person having connections to the Kurdish militant Kurdistan Workers Party (PKK), which is deemed a terrorist group by Turkey, the United States and European Union.
