Turkish police have detained more than 20 Islamic State suspects, including a Syrian man believed to be organising an attack in Istanbul, a local newspaper reported on Saturday.
Police arrested the man, identified as Ali al-Aggal and codenamed Azzov, believed to be the IS group’s organiser of Turkey attacks, in an operation in the capital Ankara, Haber-Turk newspaper reported.
In a separate raid, police held 24 other IS suspects from Iraq and Syria in Kucukcekmece district of Istanbul, the newspaper said.
It said nine of the suspects were suspected of having direct contacts with al-Aggal and were awaiting explosives and ammunition from him in order to carry out an attack in Istanbul.
The remaining 15 suspects were planning to cross the Turkish border into conflict zones, the newspaper said.
Police found out that suspected IS jihadists used the building in Kucukcekmece as a “sleeper cell” and seized many documents and digital materials allegedly belonging to the extremist group, according to the report.
Turkey has suffered a series of attacks blamed on IS jihadists, including a suicide bombing at a Kurdish wedding in a city close to the Syrian border in August.
The latest arrests come as several embassies, including Britain’s, closed Friday for security reasons.
A member of the anti-IS coalition led by the US, Turkey has started to take an active role in the fight against the group after it had long been criticised by its Western allies for not doing enough.
Turkey in recent months has cracked down on the group’s sleeper cells and launched an ambitious operation inside Syria to oust jihadists and Syrian Kurdish militia from its frontier.
President Recep Tayyip Erdogan has indicated that Turkey and the US have discussed an operation to push IS jihadists out of their de facto capital of Raqqa in Syria but there have been no further details.
