The soldier died on Monday in Senegal's capital Dakar, where he was taken for treatment with two other peacekeepers after a vehicle they were travelling in hit a roadside bomb on November 22, it said in a statement.

The attack occurred 11 kilometres (7 miles) from a UN base in Tessalit, a town in the desert north of the Sahel state.

"I bow to the memory of our late colleague, who paid with his life in the quest for peace in Mali," El-Ghassim Wane, who heads the UN mission in Mali, known as MINUSMA, was quoted in the statement as saying.

The statement did not mention the soldier's nationality.

Mali has been struggling to contain a jihadist insurgency that first emerged in the north of the country in 2012, before spreading to the centre as well as neighbouring Burkina Faso and Niger.

Thousands of soldiers and civilians have died in the conflict to date, and hundreds of thousands have been forced to flee their homes.

Deployed in Mali since 2013, MINUSMA is currently the deadliest United Nations peace mission in the world, with 146 killed in hostile acts recorded as of October 31, according to UN statistics.

The latest death comes after an Egyptian peacekeeper was killed by a roadside bomb in northern Mali in October.

Laying roadside bombs -- or improvised explosive devices -- is a common tactic of jihadist groups in the region.

On Sunday, an UN base in the northern city of Gao also came under mortar fire.
