Pop star and Twitter addict M.I.A. has taken to the social networking site once again, this time to pick a bone with CNN anchor Anderson Cooper.

In a tweet earlier this week, the highly political British singer of Sri Lankan descent said, regarding the Brit documentary "Sri Lanka's Killing Fields," that someone "should make @andersoncooper watch it / film it and show the world what happens when respected journos get it wrong #killingfields."

Her next tweet clarified why she singled Cooper out, claiming that he once called her "a terrorist for speaking out" on the lengthy and grisly Sri Lankan Civil War waged between the government and the Tamil Tigers.

Her accusations triggered a Twitter war, in which Cooper defended himself by saying, "@miauniverse, you are mistaken. I never called you a terrorist. I don't even know who you are other than the lady who sang at superbowl," adding "By the way, I defended your finger pointing at the superbowl, so check your facts. I've no idea what youre tweeting about."

It turns out that in 2009, a blog associated with Cooper's show linked to an external article that called M.I.A. a "Lady Tamil Tiger" who was raising "international support for a terrorist organization." 

The two made up, with Cooper offering this olive branch, "@miauniverse I can understand your frustration if someone wrote untrue things about you, and I'm glad you were able to respond. And the brutal war in SL has not gotten enough coverage in the US, and I know that very upsetting."  

M.I.A. responded, "@andersoncooper im glad u understand but please watch #killingfields because this is what i was trying to say."

If only all wars were so easily resolved.
