FIFA president Sepp Blatter has expressed his shock after the heads of Somalia's football federation and Olympic committee were both killed in a suicide bombing attack. Somali FA president Said Mohamed Nur and Somali Olympic Committee president Aden Yabarow Wiish died after the blast on Wednesday in the national theatre in Mogadishu. Blatter said in a statement: "I am shocked to hear about the attack that has today taken the lives of several people in Mogadishu, including the president of the Somali Football Federation Said Mohamed Nur and Somali Olympic Committee president Aden Yabarow Wiish. "I knew both men personally and can only say good things about their endless efforts to promote sport and football in their country. They will be sorely missed. "At this very sad time, my thoughts and those of FIFA and the worldwide football community are with the families and loved ones of all the victims of this attack, and especially to the football and sport family of Somalia.'' The two officials had only just inspected the reconstruction of the national stadium in Mogadishu after years of civil war in Somalia.
