MOSCOW, March 24 - The dispute between Russian and Ukraine over the PrikarpatZapadtrans pipeline system, part of the Transnefteprodukt system, is threatening to bring the transit of oil products to Europe to a halt.

"As a results of the actions on Ukraine's part, a situation has now developed that could produce a suspension of the oil-product pipeline system's operations on Ukrainian territory," Transnefteprodukt said. "This oil-product pipeline system is of great significance, as it provides transit-transportation for oil products bound for the European consumer," the company said.
