Nord Streams Terrorist Attack Involves Professional Military: Slovak PM

"This was clearly a terrorist sabotage operation, which must have involved the most professional military units," the prime minister said.

Fico added that the Nord Stream explosions raise questions about whether something larger than Ukraine itself is at the core of the Ukrainian conflict, TASS reported.

The prime minister noted that a group of individuals "hovering near the Druzhba oil pipeline and tracking it with drones" was recently uncovered in Slovakia, an incident discussed at the Slovak State Security Council.

"I wouldn’t be surprised if someone attacked a gas pipeline or our oil pipeline to prevent the import of raw materials from the east, pushing instead for all supplies to come from the West," Fico said.
