Ugandan police discovered an unexploded suicide belt and arrested several individuals following bomb attacks that killed 74 soccer fans while they were watching the World Cup final on television. Somali Islamists with ties to al Qaeda have claimed responsibility for the attacks. Uganda's opposition has called for the withdrawal of the country's peacekeepers from Somalia. A government spokesperson reported that an unexploded suicide belt was found at another location in the capital city of Kampala, following the twin explosions at two bars full of soccer fans on Sunday night. Arrests were made after the discovery of the unexploded belt in the Makindye area. He did not provide details on the number or origin of those arrested. Coordinated attacks like these are typically 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 AMISOM in Somalia. Uganda's FDC party has called on President Museveni to withdraw soldiers and stated they would do so if they won the upcoming elections in 2011, as they believe Uganda has no strategic interest in Somalia where there is no peace to maintain. FDC spokesman Wafula Oguttu told Reuters that they are sacrificing their children for no reason, and their goal is to remove troops once they come to power. AMISOM stated that the explosions would not impact their mission in Somalia, where they protect the presidential palace and secure Mogadishu's airport and port. The FBI is investigating the coordinated explosions, marking the first time al Shabaab has expanded its violent efforts 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 internationally. Foreign direct investment has increased in the third largest economy in East Africa, mainly due to oil exploration near the border with the Democratic Republic of Congo. According to analysts, a sustained bombing campaign could harm Uganda's investment environment, but a single attack is unlikely to deter major companies like Tullow Oil from investing. The United States, which had a citizen among the casualties, has offered assistance with the investigations, with three FBI agents currently collecting evidence on the ground and an additional team ready to deploy to the country if needed. Opolot stated that there were no indications that the African Union summit scheduled to be held in Uganda this month would be called off due to the bombings.
