Ugandan authorities discovered an unexploded suicide vest and made several arrests following bomb blasts at two bars that killed 76 soccer fans watching the World Cup final. Al Shabaab Islamists, reportedly linked to al Qaeda, claimed responsibility for the attacks, although a militant group official denied the involvement of suicide bombers. The vest, found in Makindye on Monday, resembled evidence from the other blast sites in Kampala. Police stated that the vest was designed to be planted as an improvised bomb, rather than worn. A man named Yonis, who is an assistant to al Shabaab spokesman Sheikh Ali Mohamud Rage, stated in a telephone interview with Reuters that the presence of planted bombs indicates that there was no suicide bombing. Coordinated attacks are a common strategy used by groups associated with al Qaeda and Osama bin Laden. If it is proven that these attacks were carried out by al Shabaab, it would mark the first time the militants have extended their influence beyond their borders. Analysts have raised concerns about the possibility of assistance or funding from individuals in Uganda or foreign militants within al Shabaab. "The impact remains unchanged whether they are Somalis or foreigners. According to Abdi Samatar, an expert on Somalia from the University of Minnesota, it is the foreign elements that now control the al Shabaab project." Kayihura did not provide additional information on the number or origin of the detained suspects. He also increased the death toll to 76 from 74. The al Shabaab militants have warned of additional attacks unless Uganda and Burundi pull out their peacekeepers from AMISOM." They have control over large portions of the southern and central regions of the chaotic nation, but the regional bloc, IGAD, has stated that they will not back down in the face of threats. They will continue to support the government in Somalia, which is backed by Western powers. The executive secretary of IGAD, Mahboud Maalim, announced plans to increase peacekeepers in Somalia to over 8,000, with hopes of having the additional troops deployed by the second week of August. IGAD members, including Kenya, Uganda, Sudan, Ethiopia, Somalia, and Djibouti, have expressed a desire for 20,000 troops from the AU and United Nations to be stationed in Somalia. Meanwhile, Uganda's opposition party, Forum for Democratic Change (FDC), has called on President Yoweri Museveni to withdraw his peacekeepers and has stated plans for a withdrawal if they win the 2011 elections. FDC spokesman Wafula Oguttu told Reuters that Somalia does not have peace to maintain and Uganda does not have any strategic interest there, so sacrificing their children for nothing. Analysts believe that a sustained bombing campaign would harm Uganda's investment climate, but a one-time attack would not deter major companies like Tullow Oil from investing. Foreign direct investment in Uganda has increased due to oil exploration along the western border with the Democratic Republic of Congo. The US State Department confirmed that an American was among the casualties and had three FBI agents at the scene collecting evidence. Opolot mentioned that there was an extra team ready to be sent out. He also stated that there were no indications of the African Union summit, which is scheduled to be held in Uganda this month, being called off due to the bombings.
