A grenade exploded near a bus station in Rwanda's capital late Wednesday, wounding at least seven people in an attack that came two days after the country's presidential election, AP quoted a police spokesman as saying. The election commission said Wednesday that full provisional results showed President Paul Kagame was re-elected with 93 percent of the vote and that turnout was 97 percent. Kagame has overseen strong economic growth in Rwanda but has been criticized for crackdowns on dissent and opposition groups. Opposition parties were banned from the vote and some Rwandans said they were forced to cast ballots for him. Police spokesman Eric Kayiranga said seven people were hospitalized for injuries after the grenade explosion, including two seriously. Witnesses earlier had estimated around 20 people were wounded. At the scene of the blast, there were blood stains on the ground and a motorbike lay in the street. «I saw a grenade (rolling) past and then I felt myself falling down,» Michael Mugisha, a student who had blood on his shirt and a bandage under his right eye, said at the hospital. «People were running. There were so many people.»
