South Korea's consumer prices rose 2.0 percent in October, driven by an increase in prices in the service and agricultural sectors, a report showed Monday.

The figure represents a slight drop from the 2.2 percent year-on-year gain tallied in August and September, Yonhap News Agency said, quoting the report by Statistics Korea.

Prices for the service sector rose 2.0 percent from a year before, with farm and fisheries prices moving up 5.5 percent, the report said.

Industrial prices edged up 1.1 percent from a year ago, it added.
