24 Janauary 2012: Islamist militants have launched a suicide truck bomb attack on an Ethiopian military base in central Somalia, witnesses say.  Al-Shabab says it killed 10 Ethiopian soldiers in the attack in the town of Beledweyne but this has not been confirmed.  Ethiopian forces seized Beledweyne from al-Shabab last month.  Kenyan troops have also entered Somalia to battle the al-Qaeda linked group which still controls many areas.  Beledweyne is a strategic town, 30km (20 miles) from the Ethiopian border on the main road to the capital, Mogadishu, and also on the major artery linking the north and south of the country.  "There was a heavy explosion that shook the whole the city," local security official Mohamed Osman told the AFP news agency.
