Content security policy violated when opening a link inside an iframe

Hi,
I am getting the following error in my console of firebug
Content Security Policy: The page's settings blocked the loading of a resource at http://www.google.com/ ("frame-src data:").
This error happens when i click on a link on my page which is loaded inside an iframe.. Following screenshot will better explain it :
Here is the HTML of my page :
what actually i want is that this opens in a new tab or a new window altogether.
I guess whats happening is that this is getting loaded inside the iframe and so content security policy is getting kicked in .

Here is the header for my page which has csp :
This www.google.com is just an example.. there can be any link in the iframe...
How should i handle this ?

Thanks
