An injured victim of an explosion lies on the floor while being attended at the Kenyatta National Hospital in Nairobi, on June 13, 2010. A double explosion of unknown origin ripped through a political gathering in Nairobi Sunday against a proposed new constitution for Kenya, injuring at least 24 people, police said. The two blasts occurred in the middle of the crowd in Uhuru (Freedom) Park in the heart of the capital during prayers at the end of the rally, called by evangelical Protestant churches, said Nairobi police chief Anthony Kibuchi..
