NAIROBI (AFP) ― A U.S.-born Islamist fighter viewed as a key foreign leader within Somalia’s Shebab militia allied with al-Qaida says he fears his life is now in danger from fellow extremists.

Omar Hamami ― better known as Abu Mansoor al-Amriki ― gave the warning in an undated video posted on several Somali websites and YouTube Saturday.

“To whomever it may reach from the Muslims, from Abu Mansoor al-Amriki, I record this message today because I feel that my life may be endangered by Harakat Shebab al-Mujahideen due to some differences that occurred between us regarding matters of the Shariah (Islamic law) and matters of the strategy,” he said, speaking in English.

The bearded Amriki, dressed in a black top and a checkered keffiyeh headscarf, posed in front of the Shebab’s black flag and beside an automatic rifle in the minute-long video, but did not confirm his location.
