Ugandan police discovered an unexploded suicide belt and made multiple arrests following the deaths of 74 soccer fans in twin bomb attacks during the World Cup final. Somali Islamists with ties to al Qaeda claimed responsibility for the attacks. Uganda's opposition has called for the withdrawal of peacekeepers from Somalia. A government spokesperson reported the discovery of the unexploded suicide belt in Kampala, following the explosions at two bars on Sunday. Arrests were made after the belt was found in the Makindye area. He did not provide details on the number or origin of the people who were arrested. Coordinated attacks like these are often 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). The opposition Forum for Democratic Change (FDC) in Uganda has called on President Yoweri Museveni to withdraw his soldiers and stated that they would do so if they were to win the upcoming elections in early 2011. They believe that there is no peace to be kept 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 and their goal is to remove their troops as soon as they take power. AMISOM stated that the explosions will not impact their mission in Somalia, where they protect the presidential palace from insurgent attacks and secure Mogadishu's airport and port. The FBI is investigating the coordinated blasts, which mark the first time al Shabaab has extended its violent quest for power beyond Somalia. Analysts warn that the group's threats should be taken seriously, as they have shown the capability and determination to carry out attacks abroad. Foreign direct investment in the third largest economy in East Africa has increased significantly, largely 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 environment, but a one-time attack is unlikely to deter major companies like British hydrocarbons explorer Tullow Oil. An American was killed in the attack, and the United States has offered assistance with the investigation, with three FBI agents already on the ground collecting evidence and another team ready to deploy if needed in the east African nation. Opolot stated that there was no indication that the African Union summit scheduled to be held in Uganda this month would be called off in light of the bombings.
