The remains of four of Kenya's fallen soldiers were yesterday airlifted from Somalia to Nairobi, as it emerged that al shabab militants are holding an unknown number of soldiers hostage. Earlier, sixteen soldiers were airlifted to Nairobi following a search and rescue operation in El Adde. Kenya is yet to give casualty figures following Friday's assault on African Union military base in Somalia. Kenya's Defence Secretary , Raychelle Omamo, says more bodies are expected in Nairobi within the course of the week. Sarah Kimani reports.
