In the latest development in the US presidential race, Republican candidate Mitt Romney has claimed that President Barack Obama is running a campaign of hatred.

The latest offensive is a new angle in his campaign to denigrate the president after losing ground in recent weeks.

The presidential hopeful lashed out against his political opponent after a TV campaign aired by Obama's supporters accused Romney of playing a part in the death of a woman during his time in the business sector.
