MOSCOW, April 7 (Reuters) - U.S. oil major Chevron said on Tuesday that crude oil exports from the vast Tengiz field, Kazakhstan's largest, continued uninterrupted.

Chevron issued the comments after Russia's defence ministry said on Monday that Ukraine had attacked facilities at the maritime transhipment complex of the Caspian Pipeline Consortium, which handles oil from Kazakhstan, including from Tengiz, in the port of Novorossiysk.
