Mortar shells hit the presidential palace of a Somali regional state on Saturday after the election for a number of federal parliament seats started there under heavy security.
Al-Qaeda-aligned militant group of Al-Shabab claimed responsibility via its media affiliated wing, Radio Andalus.
Regional authorities have not immediately commented on the mortar attacks.
Several mortar bombs hit the presidential palace of Somalia’s Southwest state in the town of Biadoa where voting for a number of parliament seats were to commence shortly.
Casualties have not been immediately clear, but the assault caused hours of delay in the election.
Ethiopian military base at the airport of Baidoa was also among other targets hit by the mortar shelling.
Authorities did not say whether there were casualties among troops stationed in the military camp.
