A series of battles in Hiraan, Shabeellaha Dhexe and Galgudug, between rebels of al-Shabaab and Hizbul Islam and Somali government forces and ICU militants loyal to the government, erupted during spring 2009. The fighting led to al-Shabaab capturing major government strongholds and Ethiopian forces re-entering Somalia and setting up bases in Hiraan. There was a halt in fighting during a government offensive in Mogadishu, which started on May 22.
