Serbia: Explosive materials of high destructive power were found near a gas pipeline connecting Serbia and Hungary, Serbian President Aleksandar Vucic said Sunday after speaking with Hungarian Prime Minister Viktor Orban. Suspicious objects were discovered near the villages of Velebit, Tresnjevac, and Vojvoda Zimonjic in the municipality of Kanjiza, in close proximity to critical gas infrastructure, according to local media reports.

According to Anadolu Agency, around 140 police and military personnel have been deployed to the area, with search operations ongoing under the supervision of the Higher Public Prosecutor's Office in Subotica. Authorities have blocked several roads in the municipality, while the operation is being conducted both on the ground and from the air, with helicopters monitoring the area.

Vucic said investigators found explosive materials along with devices needed for their activation and informed Orban about initial findings during a phone call. He added that Hungarian authorities would be kept updated as the investigation continues into potential threats to critical infrastructure.

Orban confirmed the development, saying Serbian authorities had found explosive materials and activation devices near the pipeline, and announced he had convened an extraordinary defense council meeting. Hungarian Foreign Minister Peter Szijjarto also confirmed that they received a report that "someone tried to blow up the Turkish Stream gas pipeline in Serbia," stressing that the pipeline "will guarantee Hungary's secure gas supply."

"We reject in the strongest possible terms any attack on our sovereignty, because an attack on the security of our energy supply cannot be interpreted as anything other than an attack on our sovereignty," Szijjarto said in a statement issued by government spokesman Zoltan Kovacs on US social media company X.

Separately, prosecutor Mladenka Manojlovic Gajin told Serbian broadcaster RTS that they investigated the section of the road between Gornji Breg and Vojvoda Zimonjic. She said they found two backpacks containing about four kilograms of material, "which is assumed to be plastic explosives," along with suitable material for the assembly of an explosive device. "The crime is qualified as a criminal offense of illegal production, possession, carrying, and trafficking of weapons and explosive materials in connection with the crime of diversion. In the future, all necessary actions will be taken to find the perpetrator of these crimes," she added.
