The price of Kuwaiti crude oil decreased USD 64 cents to reach USD 104.51 per barrel (pb) on Friday, Kuwait Petroleum Corporation (KPC) said on Saturday. Comparatively, the price was USD 105.15 pb on Thursday, it said, according to Kuwait News agency (KUNA). The fall in Kuwaiti crude prices comes at a time when world oil prices are up and down due to several reasons, primarily the Greek credit crisis. (QNA) LY
