Police in Istanbul fired teargas and water cannon when a demonstration by protesters blaming the government for a suspected Islamic State suicide bombing turned violent, a Reuters witness said.
Hundreds gathered near Istanbul's central Taksim Square after the bombing in the mostly Kurdish border town of Suruc which killed at least 30 people.
Some chanted slogans against President
Tayyip Erdogan and the ruling
AK Party, including: "Murderer Islamic State, collaborator Erdogan and AKP."
Turkey's Kurds have been enraged by what they see as
Ankara's failure to do more to stop Islamic State. The PKK Kurdish militant group earlier said it held the government responsible for Monday's attack, saying
Ankara had "supported and cultivated" Islamic State against the Kurds in
Syria.
The demonstration in
Istanbul had largely been peaceful, but some protesters threw bottles at police, the witness said.
