Ugandan police discovered an unexploded suicide belt and made multiple arrests following the deaths of 74 soccer fans in two bomb attacks during the World Cup final. Somali Islamists associated with al Qaeda claimed responsibility for the attacks. Uganda's opposition has called for the withdrawal of peacekeepers from Somalia. A government official reported that the unexploded suicide belt was found in a different location in Kampala, a day after the bombings at two bars filled with soccer fans. "Arrests were made after the discovery of the unexploded suicide belt in the Makindye area," stated government spokesman Fred Opolot. He did not provide details on the number or origin of those arrested. Coordinated attacks, similar to those seen in al Qaeda and groups associated with Osama bin Laden's network, have been a common tactic. The al Shabaab militants have threatened further attacks unless Uganda and Burundi remove their peacekeeping troops from Somalia. The opposition Forum for Democratic Change party in Uganda has called for President Yoweri Museveni to withdraw soldiers from Somalia, stating that there is no peace to be upheld and Uganda has no strategic interest in the region. FDC spokesman Wafula Oguttu told Reuters that they are sacrificing their children for no reason, with the objective of withdrawing troops immediately after gaining power. Despite the explosions, AMISOM stated that it would not impact their mission in Somalia, where they protect the presidential palace and the airport and port in Mogadishu. The FBI is now investigating the coordinated blasts, marking the first time al Shabaab has extended its violent tactics beyond Somalia. Analysts warn that the group's threats should be taken seriously, as they have shown the capability and determination to launch attacks abroad. Foreign direct investment in the third largest economy in East Africa has increased significantly due to oil exploration on the western border with the Democratic Republic of Congo. Analysts believe that a sustained bombing campaign could harm Uganda's investment environment, but a single attack is unlikely to deter major companies like British hydrocarbons explorer Tullow Oil from investing. An American citizen was killed in the attack, and the United States has offered assistance with the investigation by sending three FBI agents to collect evidence. Another FBI team is ready to be deployed to the East African nation if needed. Opolot stated that there was no indication that the African Union summit scheduled to be held in Uganda this month would be called off due to the bombings.
