United States Democratic presidential candidate John Kerry said on Friday that he will "stop at absolutely nothing to hunt down, capture or kill the terrorists" in response to a video statement made by Osama bin Laden.

"As Americans, we are absolutely united in our determination to hunt down and destroy Osama bin Laden and the terrorists. They are barbarians and I will stop at absolutely nothing to hunt down, capture or kill the terrorists wherever they are, whatever it takes," Kerry said in a statement.

"There will be no negotiations with the terrorists," the statement said.
