Uganda and Burundi have put two battalions on standby to send to war-torn Somalia to fill the gap left by withdrawing Ethiopian troops, a Ugandan army spokesman said Friday. "There is no time framework under which we will send our soldiers there," Major Felix Kulayigye told Deutsche Presse-Agentur dpa. "We have a battalion ready, and it is just a matter of waiting for the logistics and then we will go." Ethiopia is pulling its forces out of Somalia after a two-year occupation that has failed to defeat Islamist forces, reported dpa. [...] The United Nations World Food Programme (WFP) warned on Thursday that it might have to stop distributing food in Somalia if the safety of its staff cannot be guaranteed. Two WFP aid workers were shot in early January, adding to another five killed last year.
