Violence has flared on election day in Kenya, with at least 13 people killed in co-ordinated attacks on the coast. A group of 200 Mombasa Republican Council (MRC) secessionists armed with guns, machetes and bows and arrows set a trap for police before dawn, killing five officers, the Kenyan police inspector general, David Kimaiyo, said. One attacker also died. A second attack by secessionists in nearby Kilifi killed one police officer and five attackers, Kimaiyo said. A Kilifi police official, Clemence Wangai, said seven people had died in that assault, including an election official. The separatist group denied any responsibility for the attacks, however. “We are not responsible for any attacks anywhere in this region,” the MRC spokesman Mohammed Rashid Mraja told the Reuters news agency, adding that the group only sought change through peaceful means. Kenya is facing a huge test as it seeks to avoid a repeat of the ethnic violence left more than 1,100 people dead and 600,000 displaced following the 2007 election. Officials, candidates and media have made impassioned pleas for peace this time.
