KIEV, Aug. 29 – The Anti-Monopoly Committee fined Luk-Avia-Oil and Krebo, the country’s two jet fuel suppliers, for overcharging airlines while selling jet fuel late last year, the committee reported on Wednesday.

The action against Luk-Avia-Oil, a subsidiary of Russian oil major Lukoil, and Krebo, a subsidiary of UkrTatNafta, Ukraine’s No. 1 oil refinery, will force both companies to lower jet fuel prices.
