Serving and former US Navy SEALs have slammed President Barack Obama for taking the credit for killing Osama bin Laden and accused him of using Special Forces operators as ‘ammunition’ for his re-election campaign.

The SEALs spoke out to MailOnline after the Obama campaign released an ad entitled ‘One Chance’.

In it President Bill Clinton is featured saying that Mr Obama took ‘the harder and the more honourable path’ in ordering that bin Laden be killed. The words ‘Which path would Mitt Romney have taken?’ are then displayed.
