Qatar's ruler is seeking to assure energy consumers that the unrest roiling the Arab world this year will not affect supplies of oil and natural gas.

But the emir says the region's major energy producers will "exert every effort" to ensure energy supplies continue to flow, especially in time of crisis. (AP)
