Tunisia's annual inflation rate rose to 6.0 percent in July from 5.7 percent in June, hitting its highest rate this year, official data showed on Thursday. Inflation has been rising for the last four months, boosted by rising prices for food and clothing. Tunisia's central bank in June raised its key interest rate to 4.75 percent from 4.5 percent to counter inflation, in its second rate hike in six months. Food and drink prices climbed 7.9 percent year-on-year, while clothing and footwear prices gained 7.3 percent, the data showed. July's inflation rate matched December's 6.0 percent reading.
