Hammami allegedly travelled to Somalia in 2006, where he is believed to be, and joined al-Shabaab’s military wing before rising to be a leader in the organisation, according to the FBI.
The US State Department designated al-Shabaab, which is now affiliated with al-Qaeda, as a terrorist group in 2008. The group has “repeatedly threatened terrorist actions against America and American interests,” the FBI said in a statement.
Hammami, who has been indicted in the United States on various terrorism charges, has been the subject of an international arrest warrant since 2007.
He recently released a video online calling on the “leaders of jihad” to intervene and find a solution to the “the bitter situation that currently engulfs the Somali [foreign fighters]“.
