MOSCOW, April 2 (Reuters) - Russian restrictions were

imposed Black Sea oil exports from the Caspian pipeline due to

Ukrainian drone attacks on the pipeline's infrastructure, the

Kremlin said on Wednesday.

Russia ordered the Black Sea terminal handling Kazakhstan's

oil exports pumped by U.S. majors Chevron ( CVX ) and Exxon

Mobil ( XOM ) to close two of its three moorings earlier this

week following snap inspections by Russia's transport watchdog.
