Turkish Prime Minister Ahmet Davutoglu says the Islamic State group is behind the suicide attack in Istanbul that killed 10 people, mostly German visitors.

Davutoglu said Tuesday that Turkey is determined to battle the militant group until it no longer “remains a threat” to the country or the world.

Turkish authorities have said a 28-year-old Syrian national carried out the attack in Istanbul’s historic Sultanahmet district, a main tourist hub.
A senior Turkish government official says at least nine of the 10 people who died in Tuesday’s suicide bombing in Istanbul’s historic district were German nationals.
