Protester dragged from Obama rally in Cincinnati, Ohio

In the last few hours of campaigning before Tuesday's US presidential election, Barack Obama was interrupted twice by hecklers at a supporters' rally in Cincinnati, Ohio.

The first man is believed to have shouted several statements about abortion while holding up a placard showing images of foetuses.

Many in the crowd applauded when police officers eventually prised his fingers from a railing and carried him from the venue.

A second heckler who shouted and made gestures towards Obama was booed and subsequently led away.

A third interruption was more positive with a fan shouting, "We love you!" - the president responded, "I love you back!"
