Turkish police have detained 20 foreign nationals suspected of links to ISIS, the country's state-run news agency has said.
Anadolu Agency said on Monday that the suspects were detained in the capital Ankara by anti-terrorism police. There was no immediate information on their nationalities.
The sweep came a day after the US announced that ISIS leader Abu Bakr Al Baghdadi was killed in a raid in Syria.
Turkey was hit by a wave of attacks in 2015 and 2016 blamed on ISIS and Kurdish militants that killed around 300 people.
In the last major attack, 39 people were killed when a gunman opened fire at an Istanbul nightclub during New Year celebrations in the early hours of 2017. The attack was claimed by ISIS.
