The African Union said Saturday that AU and Somali troops have expelled al-Shabab militants from two more districts in the capital.
The AU force also said the body of a suspected militant from Pakistan was recovered after fighting Saturday.
Col. Paul Lokech, a Ugandan commander, said the militants have been pushed back from Villa Somalia, where the Somali government is housed, and that they no longer pose a threat against the government seat.
Somalia has not had a fully functioning government in two decades. The recent offensive against al-Shabab has succeeded in reducing the militants' territory.
