The U.S. military in Iraq says one U.S. soldier has been killed and three others wounded in a bomb attack in the country's north.

In a statement, the military said the bomb was detonated Monday near a military patrol near the town of Baquba.

The violence came as President Bush joined other world leaders in praising the results from Iraq's national elections.

World leaders hailed the election results, but several also urged the winning parties not to worsen religious and ethnic tensions in the country.

The United Iraqi Alliance, a coalition of Shi'ite Muslim groups, won the biggest share of the eight million votes, but fell just short of an outright majority.

Iraq's election commission says a Kurdish coalition finished second, with 25 percent. Interim Prime Minister Iyad Allawi and his allies ranked third, with 14 percent.
