Unknown fighter jets fired several missiles at small villages located in Lower Shabelle region, south of Somalia on Wednesday night, residents said.

The air raid was followed by a ground offensive by foreign forces, along with Somali national army soldiers who swept into the locations targeting Al-Shabaab hideouts.

Heavy gunfire exchanging between the allied troops and militants was heard after the undercover attack on Bariire area, where a US soldier was killed last year during operation.

One of the missiles fired by the warplanes was reported to have struck a mosque in the locality. At least 8 residents lost their lives in the attack by Somali and the foreign forces.

The scene has been the flashpoint of clashes and airstrikes in the past few years.
