MOSCOW, Dec 31 (Reuters) - Russia's Gazprom said that it

will send 37.2 million cubic metres of gas to Europe via Ukraine

on Tuesday, compared to 42.4 mcm on Monday.

Supplies of Russian gas via Ukraine are due to stop from the

early hours of Jan. 1 after the current five-year transit deal

between Moscow and Kyiv expires. Kyiv has refused to negotiate a

new agreement as its war against Russia approaches the end of a

third year.
