The Somali al-Qaeda affiliate, al-Shabab, has executed an American terrorist according to media reports in Somalia.

The al-Qaeda-allied group al-Shabaab executed US-born jihadist Omar Hammami on April 5th, according to unconfirmed Somali media reports.

Hammami, known as Abu Mansour al-Amriki, said he feared for his life from other al-Shabaab leaders because of strategic and ideological differences in a statement released last month.

According to Somalia's Gedo Online, Hammami was the only one absent from a recent meeting attended by top al-Shabaab leaders in Baraawe.

Al-Shabaab reportedly hunted down Hammami after he left Marka in the Lower Shabelle region. He was reportedly beheaded on the spot and buried somewhere between Marka and Baraawe.

According to the report, the alleged execution angered some al-Shabaab leaders, who accused al-Shabaab leader Ahmed Abdi Godane of ordering the execution.

A group of foreign fighters and other top al-Shabaab members, including Fuad Mohamed Khalaf, also known as Fuad Shongoole, reportedly fled to the Galgala Mountains following the news of the execution.

Hammami grew up in Alabama and turned jihadist sometime after he dropped out of college in 2002. He traveled with a friend to Somalia and joined up with the al-Shabab terrorist outfit.

Huffington Post reports that Hammami feared for his life from his comrades due to disputes over the interpretation of Sharia law.

Hammami, known as Abu Mansur al-Amriki, or "the American," appears in a video saying he has disagreed with his comrades in the al-Qaida-linked al-Shabab militia on Islam's Sharia law and strategy. The authenticity of the video could not be independently verified.

He thumbed his nose at the US because of several erroneous reports that he had been killed in drone attacks. He isn't laughing anymore now that his head has been separated from his body and his carcass dumped into an unmarked grave.

May all American-born jihadists enjoy the same fate.
