ISTANBUL (Dispatches) -- 
Turkish security forces arrested 41 suspected members of the Gülenist Terror Group (FETÖ) in coordinated operations across 32 provinces, the Interior Ministry announced Monday, while President Recep Tayyip Erdogan arrived in Seoul for a state visit expected to focus on nuclear energy and defense cooperation.
The Interior Ministry said gendarmerie units under the coordination of the Gendarmerie General Command’s Counterterrorism Department and public prosecutors’ offices detained 72 suspects in raids spanning major cities including Istanbul, Ankara, Izmir, Bursa, Adana and Gaziantep. 
Of those, 41 were formally arrested while judicial proceedings against the remaining suspects continued.
The suspects were allegedly involved in the group’s ongoing organizational activities, maintained contact with senior operatives, and provided financial support to organizations affiliated with FETÖ, according to the ministry. 
Some were also accused of spreading terrorist propaganda through social media platforms. Security forces seized numerous organizational documents and digital materials during the raids.
The operations come more than a decade after the July 15, 2016 coup attempt, which killed 251 people and injured nearly 2,200 others. Tens of thousands have been detained, arrested or dismissed from public sector jobs following the attempt under a state of emergency.
Separately, the Interior Ministry announced Monday that cybercrime operations conducted over the past five days across 11 provinces resulted in 120 suspects being detained, of whom 86 were arrested. 
The operations targeted qualified fraud, illegal betting, online child obscenity and abuse, and money laundering, according to a ministry statement.
President Erdogan arrived in Seoul on Monday at the invitation of South Korean President Lee Jae Myung, accompanied by Foreign Minister Hakan Fidan, Energy Minister Alparslan Bayraktar, Defense Minister Yasar Guler and other senior officials. 
The visit, running through Nov. 4, is his first to South Korea since 2018.
In a written interview with Yonhap news agency published Monday, Erdogan said South Korea is a potential partner for Turkey’s planned Sinop nuclear power plant on the Black Sea coast. 
Turkey has been conducting preliminary feasibility studies with Korea Electric Power Corp. (KEPCO), he said, adding that Ankara would consider financing, electricity costs and economic benefits before selecting a partner.
Erdogan also identified defense, semiconductors, artificial intelligence and robotics as potential cooperation areas, and called on South Korean companies to expand investment in Turkey. 
He noted the trade imbalance between the two countries — Turkey’s exports to South Korea were $1.14 billion last year versus $10.26 billion in imports — and set a target of increasing bilateral trade to $15 billion annually.
The two leaders are scheduled to hold a summit on Tuesday, with several agreements expected to be signed to strengthen the legal framework of bilateral relations.
