A new interim Afghan government was sworn in Saturday in the capital, Kabul, joining together members of the country's various factions and bringing an official end to five years of Taliban rule. 

Moments after assuming chairmanship of the interim administration, Hamid Karzai stood on a stage and swore in 29 other members of his new regime. 

Hundreds of people packed into the Interior Ministry hall on what Lakhdar Brahimi, U.N. special representative for Afghanistan, called a "momentous day" for the country and the world. 

Outgoing President Burhanuddin Rabbani said Afghanistan was now linked with modern civilization and that he was hopeful the international attention showered on the country would help it build a bright future. 

Some delegates traveling to Kabul for the installation of the interim government were in a convoy destroyed Friday night in a U.S. bombing run in eastern Afghanistan, said Yunis Qanuni, a member of the new administration. 

Qanuni, who will be interior minister, said that tribal delegates were part of the convoy, which the Pentagon said was destroyed in the strike near Khost, a town southwest of Tora Bora. Qanuni called the incident "a misunderstanding." 

Pentagon officials had said Friday the convoy was carrying al Qaeda or Taliban leaders. Responding to the new report Saturday, Lt. Col. Martin Compton of the U.S. Central Command said, "We are still looking into it."
