Kenya's inflation rate rose to 5.42 percent year on year in January from 4.51 percent in December on higher food prices, rents and school tuition costs, a source at the statistics office said on Monday.

Inflation has been rising since October when it slid to 3.09 percent, the lowest since November 2002.

The Central Bank of Kenya has a 5.0 percent medium-term target for inflation. Its Monetary Policy Committee cut the key interest rate by 25 basis points to 5.75 percent last week, saying it foresaw no upside risks to inflation.

Analysts say rising international food and fuel prices will put pressure on the inflation rate this year.

Kenyan inflation fell for most of 2010 mainly on the back of good food production and low mobile telephone tariffs.
