Turkish police detained 110 suspects and seized more than 1.28 tons of narcotics in a series of anti-drug operations carried out across four provinces centered in Istanbul, authorities said Wednesday.

The operations, conducted by the Istanbul Police Department's Narcotics Crimes Division, targeted street-level dealers as well as criminal networks allegedly involved in drug trafficking at both national and international levels.

Following 10 days of technical and physical surveillance, police launched coordinated raids across Istanbul, northwestern Türkiye, as well as the provinces of Diyarbakır and Şanlıurfa in southeastern Türkiye and Kocaeli in northwestern Türkiye.

Authorities said searches of suspects' homes and vehicles resulted in the seizure of more than 1.28 tons of narcotics, 60,000 synthetic pills, nearly 88 kilograms of chemical substances believed to be used in drug production and six handguns.

The operations led to the detention of 110 suspects. Of those, 15 were arrested and remanded in custody, while legal proceedings for the remaining 95 suspects are ongoing.
