I don't think that Creative Commons license applies unless they explcitly state that on the news site.
For example, CNN.com says "All Right Reserved" at the bottom of their page. If you check out the terms and conditions, it says "You may not modify, publish, transmit, participate in the transfer or sale, create derivative works, or in any way exploit, any of the content, in whole or in part. You may download copyrighted material for your personal use only."
MSNBC.com is even more clear on their Terms and Conditions: "You may not modify, copy, reproduce, republish, upload, post, transmit, or distribute in any way any material from this site including code and software without express permission from MSNBC or as permitted inReprint Requests ."
I'm not an expert, but taking 30% of their content does not seem to meet their rules for reproducing their content no matter if you're attributing the source or not. Perhaps a quote or two from an article is fine, but 30% sounds like a lot.
Perhaps the sites that Shahzad is using do follow Creative Commons, but many of the major news sites do not seem to do that.
