Harakat al-Shabaab al-Mujahideen (HSM) (, "The Youth" or "The Lads") is an Islamist insurgent group fighting to overthrow the government of Somalia. As of summer 2010 the group is said to control most of the southern and central parts of Somalia, including "a large swath" of the capital, Mogadishu, where it is said to have imposed its own "harsh" form of Sharia law. Estimates of al-Shabaab's strength, as of December 2008, vary between 3,000 to 7,000.
