An explosion in a highly populated area of downtown Nairobi on Sunday injured at least 29 people, and officials said an investigation is under way to determine if the blast was caused by terrorism.
Prime Minister Raila Odinga said it was too early to tell if the blast was terror related. Director of police operations, Julius Ndegwa, said it appeared no one was killed in the explosion in Kenya's capital.
Omar Alwiya, a bus conductor, said he was sleeping at around 11 a.m. when he heard an explosion that shook the room he was in and filled it with dust. He rushed to the scene and found two shipping containers overturned, several cars destroyed and a fire at a gas station.
Dr. Peter Kamau Wanyoike said 29 people were admitted to Kenyatta National Hospital. Nine had burns on 60 percent of their body. Others were injured by falling glass or minor burns.
Kenya has been on high alert since the killing of Osama bin Laden because of threats from al-Shabab militants who operate in neighboring Somalia.
