"The members of the Security Council underlined the need to bring perpetrators, organizers, financiers and sponsors of these reprehensible acts of terrorism to justice and urged all States, in accordance with their obligations under international law, and relevant Security Council resolutions, to cooperate actively with the Somali authorities in this regard," the Council said in a Wednesday statement.
Al Shabaab attacked the AMISOM peacekeeping base in the town of Janale, located in the southeastern Lower Shebelle province, on Tuesday, using an explosive-laden car. Dozens of African Union and Somali national army forces reportedly died in the attack, with more than 100 troops being unaccounted for.
"The members of the Security Council underlined that neither this, nor any other act of terrorism, would weaken their commitment to supporting the peace and reconciliation process in Somalia," the UN Security Council stressed in its Wednesday statement.
Al-Shabab seeks to overthrow the Somali government with the aim of establishing a state based on its interpretation of Islamic law. The group, which has links to al-Qaeda, has claimed responsibility for numerous attacks in Somalia and at the border towns of Kenya.
In 2006, al-Shabaab took over most of southern Somalia.
