Obama ads poke fun at Romney

President Barack Obama kept up his attack on the Republican presidential candidate Mitt Romney as the rhetoric hardened on both sides.

The Obama campaign released two new advertisements attacking Mr Romney's record as head of a private equity firm. In one of the ads, the main sound is of Mr Romney singing "America the Beautiful". The ad scrolls through lush images of Bermuda and the Cayman Islands to draw attention to Mr Romney's offshore bank accounts, while referencing the outsourcing of US jobs.

Mr Romney's campaign team criticised the ads. "Every day, President Obama hits a new low," said a spokeswoman.
