Amisom troops have just withdrawn from Garasweyne village in Bakool region leaving Al Shabaab to take occupy the area.
Ethiopian troops were in July this year accused of massacring more than 60 civilians in this region.
Some of the villages that saw much of these crimes include Wargadud, Moregabey, Garasweyne and Burdhuhule, where the Ethiopian troops reportedly carried out indiscriminate massacres.
It came after a Burundi contingent shot dead more than 20 civilians inside Marka town in Lower Shebelle region.
On Sunday, Al Shabaab launched an attack on Garasweyne forcing out Ethiopians and occupying it, according to residents.
Also today, Ethiopian troops vacated Buqaqable town in Hiiraan region fleeing leaving to retake the town which they lost to Amisom in July 2015.
Al Shabaab insurgents have also released photos showing their fighters retaking Kuntuwarey town after AMISOM forces withdrew on Friday.
In Buale town, they publicly executed four men by firing squad, accused of working for Somalia military and intelligence agencies a day ago.
Kuntuwarey town is one of the two towns the militants earlier seized in southern Somalia after launching an attack on two African Union (AU) convoys in the same region.
Both captured towns were on routes toward Indian Ocean ports south of the capital Mogadishu and came after al Shabaab fighters attacked an AU base in the same area on Sept. 1.
The other town captured in Shabelle region is El Saliindi, located 65 km (40 miles) south of Mogadishu en route to Marka.
Al Shabaab lost control of the main southern port of Kismayu and the port of Marka in 2012.
Last year, AMISOM drove al Shabaab back in the south and seized the port of Barawe in October.
Ali Nur, the acting governor of Lower Shabelle, told Reuters El Saliindi and Kuntuwarey are now controlled by the militants.
On Sept. 1, al Shabaab stormed a UPDF base in Janaale, about 90 km (55 miles) south of Mogadishu, killing at least 12 Ugandan soldiers.
Al Shabaab claimed it had killed 70 people in the assault to revenge the death of their leader, Ahmed Abdi Godane, killed in a U.S. air strike.
