More than 350 suspected Islamic State group (IS) members have been detained as part of nationwide police operations in Turkey.

Interior Minister Ali Yerlikaya said 357 suspects were apprehended across 21 provinces in coordinated raids on Tuesday morning.

This comes just a day after three police officers and six alleged militants were killed during an eight-hour siege in the northwestern town of Yalova. Another eight police officers and a security force member were injured.

Less than a week ago, authorities arrested another 115 suspects who prosecutors said had been planning attacks targeting non-Muslims during Christmas and New Year's.

Yerlikaya announced that the recent operations took place in major cities including Ankara, Istanbul, and Yalova, emphasizing the government's commitment to combat terrorism. Just as we have never given an opportunity to those who try to bring this country to its knees with terrorism, we will never give them an opportunity in the future either, he stated.

Videos shared by the minister showed extensive involvement of counter-terrorism officers during these operations.

In recent weeks, intelligence reports indicated that suspects were preparing to launch attacks on New Year's Day. Raids in Istanbul led to the seizure of documents, digital materials, and weaponry, which further demonstrated the seriousness of the threat.

In conjunction with these efforts, another 16 individuals were detained for making provocative posts on social media related to the ongoing violence.

Turkey's ongoing security measures reflect its geographical challenges, sharing a significant border with Syria, where remnants of the IS still pose a threat. Syrian President Ahmed al-Sharaa has expressed willingness to collaborate with international partners to eliminate IS remnants, while the US has ramped up airstrikes in response to the group's attacks.
