American Jihadi: Abu Mansoor Al-Amriki

Omar Shafik Hammami, also known as Abu Mansoor Al-Amriki, was a U.S. citizen and member of al-Shabaab, which [UPDATE] more recently was responsible for an attack on a Kenyan shopping mall, which left over 60 people dead.

Eventually Hammami would find himself dead at the hands of his fellow jihadi fighters. Hammami became well-known for even having a Twitter presence during the last months of his life.

There are so many unexpected twists and turns to this story. I couldn't stop watching.
