The Somali government says it has killed more than 130 fighters from the Islamist militant group al-Shabab - including top commanders.
It says a joint operation was carried out with Somalia's international partners, which include the US military.
Over the last six months the Islamic State group, which has a relatively small footprint in the country, has also lost swathes of territory as the result of an operation led by pro-government forces.
It is impossible to independently verify the details of this attack but the Somali government has described what sounds like a significant setback for al-Shabab.
