Ugandan police have discovered an unexploded suicide belt and detained several individuals following the deaths of 74 soccer fans in two bomb attacks while they were watching the World Cup final on television. Somali Islamists associated with al Qaeda have claimed responsibility for the attacks. The opposition in Uganda has demanded the withdrawal of the country's peacekeepers from Somalia. A government representative stated that the unexploded suicide belt was found in a third location in the capital city of Kampala, a day after the twin explosions occurred in two bars filled with soccer fans on Sunday night. "Arrests were made yesterday after an unexploded suicide bomber's belt was found in the Makindye area," said government spokesman Fred Opolot. He did not provide details on the number or origin of the arrested individuals. Coordinated attacks similar to this have been associated with al Qaeda and groups connected to Osama bin Laden's militant network. The al Shabaab militants have threatened further attacks unless Uganda and Burundi remove their peacekeepers from the African Union peacekeeping force in Somalia (AMISOM). Uganda's opposition Forum for Democratic Change (FDC) party has urged President Yoweri Museveni to withdraw his soldiers and stated their intention to do so if they win the upcoming elections in 2011. They argue that there is no peace to be maintained in Somalia and that Uganda has no strategic interest in the region. FDC spokesman Wafula Oguttu told Reuters that they are sacrificing their children for no reason, as their goal is to remove troops immediately after gaining power. AMISOM stated that the explosions will not hinder their mission in Somalia, where they protect the presidential palace and secure Mogadishu's airport and port. The FBI is investigating the coordinated attacks by al Shabaab as the group is now expanding its violent tactics internationally. Analysts warn that the threats from al Shabaab should be taken seriously, as they have shown they have the capability and willingness to carry out attacks abroad. Foreign direct investment has increased in the third largest economy of East Africa due to oil exploration near the border with the Democratic Republic of Congo. Analysts believe that a sustained bombing campaign could harm Uganda's investment climate, but a one-time attack is unlikely to deter major companies like British hydrocarbons explorer Tullow Oil from investing. The United States has offered assistance with investigations into the attack, with three FBI agents currently collecting evidence on the ground and an additional team ready to deploy to the country. Opolot stated that there were no indications that the African Union summit, which is scheduled to be hosted by Uganda this month, would be cancelled in light of the bombings.
