Russia is considering limiting exports of diesel and jet fuel, according to Interfax, as refinery run rates fall to multi-year lows amid Ukraine’s escalating attacks.

Oil companies were advised to curb sales of oil products to foreign markets following a Tuesday meeting with the Deputy Prime Minister Alexander Novak on the domestic fuel market, the Russian news service reported, citing several people familiar with the situation. One of the people said that the decision to ban exports of diesel and jet fuel is at an advanced stage, but the date for the ban hasn’t yet been set, according to Interfax.
