India's retail inflation in October accelerated to 6.21% year-on-year, breaching the central bank's target range for the first time in over a year, as food prices remained stubbornly high, government data released on Tuesday showed.

Food price inflation, a major contributor to the wholesale price index, rose by 11.59% annually in October, compared to a 9.47% gain in September.

Inflation rose slightly in October in line with economists' expectations, as the consumer price index was up 2.6% from a year ago and 0.2% compared with last month.
