Second Somali MP killed in two days

Unidentified gunmen shot dead a Somali lawmaker in Mogadishu Tuesday, the second Somali member of parliament (MP) killed since Monday, media reported.

Lawmaker Abdelaziz Isaq Mursal was shot dead as he left his home in the western district of Dherkenlay in Mogadishu, Xinhua reported.

The killing of the MP comes a day after lawmaker Isaq Mohamed Riino was killed in a car bomb explosion Monday.

Islamist militant group Al Shabaab has claimed responsibility for the killing of Riino and the militants vowed to continue targeting Somali government officials.

The killing of the MP was widely condemned by the Somali government, UN envoy and African Union Mission in Somalia (AMISOM).

Somali Prime Minister Abdiweli Sheikh Ahmed said the killing was a cowardly act and vowed to bring to justice those behind the deadly bomb blast.

UN Somalia envoy Nicholas Kay described the killing as a terrorist act and called for a "full investigation" of the assassination of Riino while AMISOM said the assassination was "unacceptable".

Somali government officials vowed to tackle insecurity in Mogadishu which has lately been witnessing intermittent explosions and targeted killings of both civilians and government officials.

The extremist Al Shabaab group has been pushed out of several key areas in the south and centre of Somalia by the Somali government and AMISOM forces.
