U.N. Mourns Four Staff Killed in Somalia Bomb Attack

The U.N. children's agency mourned Tuesday four staff members killed in what U.N. chief Ban Ki-moon condemned as a "barbaric attack" in Somalia.

Two of those killed in Monday's bombing in the northeastern town of Garowe came from Kenya, the other two from Afghanistan and Uganda.

UNICEF named the two Kenyans as Woki Munyui, who worked in education, and administrative officer Stephen Oduor.

Payenda Gul Abed, from Afghanistan, had been working to vaccinate children against polio, along with Ugandan citizen Brenda Kyeyune.

Two Somali guards also died, as well as the suspected suicide bomber, who destroyed the U.N. bus as it drove the staff members to work.

"Our thoughts are with the families of all who died, with those who were injured, and with all our staff who continue to work tirelessly in Somalia," UNICEF said in a statement.

"These heroes were dedicated to building a better world for children – today, all of us at UNICEF honour their sacrifice."

Five UNICEF staff members were also wounded in the attack.

Somalia's Al-Qaida-affiliated Shebab insurgents claimed responsibility, branding the United Nations a "colonization force in Somalia".
