Al-Shabaab, an Islamist militant group that has been fighting Somalia's government for a decade, said it killed more than 100 Kenyan soldiers and captured 12 others in the January 15 attack.
However, both the Kenyan government and AMISOM officials have disputed the figure, terming it a propaganda.
On Friday, al-Shabaab militants stormed an African Union (AU) base, killing dozens of KDF soldiers.

The Kenya Defence Forces (KDF) soldiers who were killed and injured in Somalia on Friday had only spent two days in that country, it has emerged.
There was no immediate comment from the Kenyan military or AMISOM, the African Union force in which the Kenyans serve.
"However, it should be noted that this is a delicate operation as we have information to the effect that some soldiers are being used as human shield, as we will not allow any further casualties", Mwathethe told journalists in Nairobi.
"This attack will not rest unanswered", she said.
General Samson Mwathethe, chief of the defence forces, said Friday's attack struck the Somali National Army base and an AMISOM base that was located in the same place, near El Adde, a town in the southwestern Gedo region. "We have engaged the perpetrators decisively and remain in full pursuit of them". A military company can range between 80 to 250 soldiers.
"Full details of those injured and killed will be made public after families affected are notified", Omamo said. A Kenyan official said on Sunday the army would issue a statement without saying when. "We have engaged the enemy and severely degraded him", he added.
Kenyan President Uhuru Kenyatta confirmed his country lost soldiers but the exact number of casualties is not yet known.
Al Shabaab said the attack was in retaliation for the Kenyan "invasion of Muslim lands".
