The sources suggest that this price increase has been done due to higher local taxes in many countries.
In addition, Apple has also introduced some new currencies to the App Store. Users from Russia, Turkey, India, Indonesia, Saudi Arabia, Israel, UAE and South Africa will now be able to purchase app in their own currencies.
