Somali military officer Abdiwahab Mohamed Ali toldPress TV that at least 390 American forces, including 38 officers have secretly reached the Mogadishu international airport.
The American troops have also set up secret jails in the country and inject dangerous drugs to Somali soldiers, according to sources.
The report came following two Friday US assassination drone attacks on al-Shabab fighters’ Harweyne training base in Elasha Biyaha on the outskirts of the capital, which claimed the lives of at least 39 people.
Earlier in January, the White House officially admitted in a report that it is launching concerted deadly attacks in Somalia as part of its campaign against the war on terror and the al-Qaeda militant group.
Washington has been using assassination drones in Pakistan, Afghanistan, Yemen, and Somalia and claims that it is targeting terrorists in the operations, but civilians have often been killed in the strikes.
