Al-Shabab formally declared allegiance to al-Qaeda in February 2010, sparking further concern that the group posed a global threat. It claimed responsibility for the July bombing at a restaurant in Kampala, Uganda, that killed about 75 people who were watching the final game of the World Cup. The bombing was intended to send a message to countries that have sent troops to support Somalia"s transitional government.
Prime Minister Omar Sharmarke, who has been criticized for failing to defeat the Shabab and who has been at odds with President Ahmed, resigned in September 2010. He was succeeded in November by Mohamed Abdullahi Mohamed.
Piracy continued to plague the waters off Somalia and other parts of eastern Africa into 2011. In February, Somalia pirates killed four Americans who were sailing on their yacht in the piracy-laden water off the coast of Somalia.
The summer of 2011 brought drought to a country already laid low by nearly constant conflict, resulting in a UN-declared famine in two regions in southern Somalia. With tens of thousands of Somalis dead of malnutrition and its related causes and ten million more at risk, those who could, fled, trying to reach neighboring Kenya and Ethiopia for help. According to a report released by the Famine Early Warning System Network (FEWS NET) and the United Nations Food and Agriculture Organizationin in April 2013, about 260,000 died in the famine—more than half under age 6. The figure is double early estimates. The report cites the delayed response by donor nations and the Shabab for not allowing the delivery of aid the affected areas.
In June, Prime Minister Mohamed Abdullahi Mohamed resigned; Abdiweli Mohamed Ali became acting prime minister and was approved by parliament and sworn in on June 28, 2011.
