The price of a barrel of Brent crude oil, the international standard, has topped $100 a barrel again just days after it spiked near $120.

U.S. benchmark crude jumped to about $95 a barrel. Markets in Asia fell back as investors absorbed the latest news suggesting the war in the Middle East is far from over. U.S. futures lost more than 1% and the dollar climbed to 159 Japanese yen while the euro fell to $1.1538.
