As many as 200 soldiers were killed in an attack on a Kenyan military camp in Somalia by al Shabaab Islamists last month, according to Somali President Hassan Sheikh Mohamud.
Kenyan authorities have refused to give a death toll following the January 15 raid, which targeted troops working under the African Union Mission in Somalia (AMISOM) near the southern Somali town of El Adde.
Newspaper pictures of coffins draped with Kenyan flags bringing back dead soldiers after the attack increased the disquiet from ordinary Kenyans and the opposition alike over Kenya's continued presence in Somalia.
"When about 200 soldiers who came to help your country are killed in one morning, it is not something trivial," Mohamud told Somali Cable TV, in an interview posted on YouTube on Thursday.
"We have been winning for years and months but that El Adde battle, we were defeated. Yes, in war, sometimes something that you do not like happens to you," he said.
