The Tanzania People's Defense Forces (TPDF) on Sunday announced the appointment of a team of experts to investigate the killing of seven Tanzanian soldiers on a peacekeeping mission in Sudan's Darfur region.

Unidentified armed assailants on Saturday ambushed a convoy composed of troops and police of the African Union and the United Nations Hybrid Operation in Darfur (UNAMID) at Khor Abeche in southern Darfur, killing the seven Tanzanian soldiers.

Colonel Kapambala Mgawe, spokesman for TPDF, said the experts will travel to Khartoum and Darfur to have talks with authorities over the deadly attack, which also left 14 others injured.

However, Mgawe declined to mention the composition of the experts and the day the team will leave for Sudan.

In February, Tanzania sent 875 soldiers to Darfur on a peacekeeping mission according to a UN declaration.

UN Secretary General Ban Ki-moon on Sunday also expressed "outrage" over the deadly attack on peacekeepers in Darfur.

In a statement issued by the UN Information Center in Dar es Salaam, the UN chief expressed his deepest sympathies to the families of the fallen peacekeepers, the government of Tanzania and all UNAMID personnel.

"The Secretary General condemns this heinous attack on UNAMID, the third in three weeks, and expects that the Government of Sudan will take swift action to bring the perpetrators to justice," said the statement.
