Donald Trump says he ordered military airstrikes on a senior Islamic State (IS) attack planner and others from the organisation in Somalia.
“These killers, who we found hiding in caves, threatened the United States and our Allies,” Trump posted on social media.
“The strikes destroyed the caves they live in, and killed many terrorists without, in any way, harming civilians.”
Trump did not name any of the people targeted in strikes.
He ended the post with: “The message to ISIS and all others who would attack Americans is that “WE WILL FIND YOU, AND WE WILL KILL YOU!”
In a statement, Defence Secretary Pete Hegseth said “our initial assessment is that multiple operatives were killed in the airstrikes and no civilians were harmed”.
The strikes “further degrade” the ability of IS “to plot and conduct terrorist attacks” and “sends a clear signal that the United States always stands ready to find and eliminate terrorists”, he added.
IS rose to international prominence in the 2010s, particularly in Syria and Iraq, but now its presence is mainly restricted to parts of Africa.
The Somali branch of IS was formed in 2015 by a group of defectors from the al-Qaeda affiliated al-Shabab group – the largest jihadist group in Somalia.
IS in Somalia is notorious for extorting locals and mainly carries out small-scale, sporadic attacks, according to the US Office of the Director of National Intelligence.
