Democratic presidential hopeful Barack Obama has called for the U.S. to dip into its strategic oil reserves to lower fuel prices in the short-term.

Both Obama and his Republican rival, John McCain, are focusing on ways of tackling the high cost of energy. It is a key issue as campaigning for November's election intensifies.

Senator Obama, speaking on his 47th birthday, put forward plans to reduce US dependence on foreign oil in 10 years.
