MOSCOW, Feb 10 Reuters Annual inflation in Russia slowed further in January, but consumer prices rose in monthonmonth terms, data showed on Friday.

Inflation has slowed since accelerating sharply after Russia began what it calls a special military operation in Ukraine on Feb. 24, a move that triggered sweeping Western sanctions and disrupted supply chains.

In January, annual inflation slowed to 11.77 from 11.94 a month earlier, data from the statistics service Rosstat showed. Analysts polled by Reuters expected a slowdown to 11.5.

The Bank of Russia targets annual inflation at 4.

Monthonmonth, the consumer price index CPI rose 0.84 after a 0.78 increase in December. In March, the index jumped 7.61, the biggest monthonmonth increase since January 1999.

The central bank on Friday kept its key rate at 7.5 and its yearend inflation forecast at 5.07.0.
