Saudi Arabia's inflation accelerated for a fourth month in April to a 10-month high of 4.9%, Reuters has reported, citing official data. The increase was attributed to global harvest concerns, as bad weather in countries that export crops to the kingdom have raised concerns over availability of supplies for some commodities such as rice. Inflation in the kingdom stood at 4.7% year-on-year in March, down from a record high of 11.1% in July 2008.
