A bomb killed at least one person at a government rally in Mogadishu's (search) soccer stadium Tuesday, exploding just as the new prime minister began his speech.

The prime minister, who had been to discuss plans to bring his government in exile back to Mogadishu from neighboring Kenya (search), was not injured and was rushed from the scene, where it appeared at least 11 people were seriously injured, according to an Associated Press reporter at the scene.

Government officials told The Associated Press that Prime Minister Ali Mohamed Gedi (search) was taken to "a safe location" north of Mogadishu. He was expected to leave Somalia later Tuesday.

Hundreds of people had gathered in the stadium to hear Gedi. Somalia has been without a central government since 1991, when clan-based warlords overthrew dictator Mohamed Siad Barre and then turned their weapons on each other.

Gedi arrived in Somalia on Friday for his first trip home since he took office. Hundreds of people had cheered Gedi when he arrived at the airport, where members of Somalia's former military formed a guard of honor for him. Trumpets sounded and the Somali national anthem played.

Islamic extremists and some of the country's dozens of warlords oppose the new government, which was formed in neighboring Kenya under the auspices of a regional bloc, the Inter-Governmental Authority on Development, and the European Union.

The government formed in 2004 has not been able to return to Mogadishu because of security fears.

President Abdulahi Yusuf Ahmed has called on the African Union to send 20,000 peacekeepers to secure Somalia and to guarantee the new government's safety and disarm the militias that currently roam the country with impunity. So far the AU has only offered to send a few thousand troops.
