Luis Moreno-Ocampo, the prosecutor of the International Criminal Court, arrived in Kenya on Thursday to announce that next month he would seek to open an official investigation into the post-election violence that rocked the country in 2008.

It was Mr Moreno-Ocampo’s first trip to Kenya since the ICC began to accelerate its work last month after the failure of Kenya’s fractious coalition government to set up a local special tribunal to try the suspects, who include senior politicians.
