The Obama administration has decided to release 30 million barrels of oil from the U.S. Strategic Petroleum Reserve as part of a broader international effort to pump more than 60 million barrels onto the world market over the next month.

U.S. Energy Secretary Steven Chu said the release of oil is a response to oil supply disruptions caused by turmoil in the Middle East and North Africa, including Libya.

The administration said the uprising in Libya has resulted in a loss of about 1.5 million barrels of oil a day. The release comes as the United States approaches a period of high energy use in July and August.

High oil prices have increased the cost of gasoline, contributing to an economic slowdown and putting increased political pressure on President Barack Obama.
