Ankara, Mar 11 (IANS): Turkish police detained 33 suspected members of the Islamic State (IS) group in operations in the northwestern province of Sakarya over alleged preparation of attacks ahead of the country's local elections later this month, a Cabinet Minister said.

The IS suspects were "preparing and searching for action before the upcoming local elections," Interior Minister Ali Yerlikaya said on Sunday on social media platform X.

The suspects were allegedly recruiting fighters to conflict zones, providing financial aid for the group, and operating illegal mosques and madrassas, the Minister added.

The police teams seized weapons, cash and organisational documents during raids, he said as quoted by Xinhua news agency report.

Turkey has stepped up operations against IS terrorists after the group attacked a church in Istanbul in late January, killing a civilian during Sunday mass.

The Turkish government designated the IS as a terrorist organisation in 2013 and blamed it for a spate of deadly attacks in the country since 2015.

In December last year, Turkish intelligence and security forces captured a top IS terrorist in charge of the group's finances in an operation in Turkey's southeastern province of Mersin.
