MOSCOW, April 2 (Reuters) - The Russian rouble weakened

against the dollar on Tuesday, hampered by reduced foreign

currency supply from exporters and as the market reacted to

another Ukrainian drone attack on a refinery deep in Russian

territory.

Ukraine struck one of Russia's biggest refineries with a

drone 1,300 km (800 miles) from the front lines in Ukraine and

said it had inflicted significant damage on a military target.

By 0836 GMT, the rouble was 0.4% lower at

92.55. Against the euro, the rouble fell 0.3% to

99.43 and dropped 0.4% to 12.73 against the yuan

.

The rouble typically loses ground at the start of each month

after exporters have paid month-end taxes for which they usually

convert their foreign currency revenues.

"Despite the decline in the supply of foreign currencies

from exporters, the further improvement of the situation on the

energy market will be a restraining factor for selling the

rouble," said Bogdan Zvarich of Banki.ru.

Brent crude oil, a global benchmark for Russia's

main export, rose 1.4% to $88.60 a barrel.

Russia's benchmark, rouble-based MOEX index slipped

0.1% to 3,360.6 points, having earlier hit its strongest since

Feb. 21, 2022, shortly before Moscow's full-scale invasion of

Ukraine.

The dollar-denominated RTS index fell 0.4%

to 1,143.9.
