IS claims attack on Syria's Raqa, alarming Kurds
The Islamic State group has claimed a suicide attack on its former Syrian stronghold of Raqa, heightening Kurdish fears of a jihadist resurgence if Turkey goes ahead with a threatened invasion.
Overnight two IS fighters armed with guns, grenades and explosive belts launched a "violent attack" on security forces in Raqa, according to the Syrian Observatory for Human Rights.
Ensuing clashes between the assailants and fighters affiliated with the Kurdish-led Syrian Democratic Forces (SDF) lasted more than one hour, the Britain-based war monitor said.
IS claimed responsibility for the assault on the Telegram messaging application.
