By News Wires (text) AFP - One person was killed and 18 injured in three simultaneous grenade attacks on public places in the Rwandan capital Kigali, national public radio said on Saturday. Five of the injured were in a serious condition following the attacks on a train station a restaurant and a building housing city centre businesses. No arrests had been made and no official reaction was issued following the attacks on Friday evening, Radio Rwanda added. Rwanda is due to hold presidential polls in August at which President Paul Kagame is widely expected to seek and secure re-election. Kagame, who heads a Tutsi-led government, has been in power since the end of the 1994 genocide by extremist Hutus of around 800,000 people, mostly Tutsis and moderate Hutus. Earlier this month, the New York-based Human Rights Watch (HRW) condemned the harassment of political opposition figures in Rwanda saying they faced increasing "threats, attacks and harassment" ahead of the poll. The group cited an incident in which Joseph Ntawangundi -- a member of the FDU-Inkingi, a new opposition party critical of government policies -- was attacked in front of a local government office. "The attack appeared to have been well coordinated, suggesting it had been planned in advance," HRW said. Ntawangundi has since been jailed after being sentenced in absentia in 2007 to 19 years by a gacaca court, one of the grassroots tribunals set up to try the perpetrators of the genocide.
