MOGADISHU, Jan 9 (Reuters) - Unknown assailants fired rocket propelled grenades at a building in Mogadishu housing Ethiopian and Somali troops, the same site where at least one person was killed in an attack over the weekend. A Reuters reporter near the building in the Kilometre Four area of the capital heard the two RPGs explode followed by five minutes of automatic weapons fire. It was not immediately clear if anyone was hurt in the attack, which a witness from a neighbouring hotel confirmed had struck the building. .
