Five African Union peacekeepers in Somalia have been arrested over alleged illegal sales of military supplies, the African Union Mission in Somalia (AMISOM) said Monday.

AMISOM said the soldiers were found in possession of fuel and sand bags and were detained Sunday in a joint operation with Somali police that followed an investigation and a period of surveillance.

A Somali military court on Monday jailed two men for life for their role in a botched laptop bomb attack on an airplane claimed by the Al-Qaida-linked Shebab.

The February 2 blast left a meter-wide (three-foot) hole in the fuselage of the Daallo Airlines plane shortly after it took off from Somalia's main airport in Mogadishu, killing only the suspected bomber and forcing an emergency landing.

U.S. special operations forces working with African partners clashed with Shebab militants in Somalia early Thursday, killing five, a U.S. defense official said. There were no U.S. injuries.

The official said the U.S. forces were advising and assisting Ugandan troops from the African Union Mission to Somalia (AMISOM) in southern Somalia, west of Mogadishu.

The African Union peacekeeping mission in Somalia (AMISOM) apologized for accidentally killing four civilians Saturday after soldiers mistook them for Shebab fighters when they failed to stop at a roadblock.

The incident happened in the area of Buulo Mareer in the Lower Shebelle region, 80 kilometers (50 miles) south of the capital Mogadishu.

At least three people were killed and six others wounded in a blast at a busy livestock market in Somalia on Wednesday, a security officer said.

The blast, the latest in a string of attacks in the war-torn Horn of Africa nation, took place in the busy Afgoye district, some 30 kilometers (20 miles) south of the capital Mogadishu.

At least five people including two children were killed on Monday in a car bomb blast outside government offices in the capital Mogadishu, a local government spokesman said.

The car, which was packed with explosives, was parked in front of shops near the headquarters of the city's local government.

Two members of Somalia's Al-Qaida-linked Shebab jihadist group were executed by firing squad Saturday for the murder of a journalist killed by a car bomb last year, a judge said.

Abdirisak Mohamed Barow et Hassan Nur Ali, who admitted being Shebab members during their trial, were shot on Saturday morning in Mogadishu, Abdulahi Hussein Mohamed, deputy judge of the supreme military court told reporters.

The Kenyan military said Sunday it killed 34 Islamic insurgents in two separate battles in neighboring Somalia this weekend.

Military spokesman David Obonyo said two Kenyan soldiers were also killed and five others wounded when Shebab militants staged an ambush in Afmadhow, southern Somalia, on Saturday afternoon.

Somalia's Shebab insurgents said Tuesday that "several" fighters had been killed in a U.S. air strike on their training camp, but disputed Washington's claims that 150 were killed.

"The enemy fired several missiles during the evening and there are several martyred mujahedeen members”, said senior Shebab commander Sheik Ibrahim Abu-Ahmed, but he added that the U.S. military's toll was "completely false."

The death toll rose to 14 on Saturday from massive bomb blasts outside a Mogadishu hotel and a park that was claimed by Somalia's Shebab Islamists, government and medical sources said.

Eighteen people were wounded in Friday's bombings, two of whom succumbed to their injuries on Saturday, Dr Mohamed Moalim of the Medina hospital in the Somali capital told AFP.
