MINUSMA commander Major General Michael Lollesgaard and the mission's police chief "escaped death in the Timbuktu region when mines on the route of their convoy wounded three peacekeepers from Burkina Faso", a civilian manager in the force told AFP.
Lollesgaard, from Denmark, and police commissioner Abdounasir Awale were on a field visit when a vehicle in their convoy hit at least one mine between the towns of Dire and Ber, a separate MINUSMA source based in Timbuktu told AFP.
An official statement from MINUSMA placed the explosion at 1:00 pm (1300 GMT), although it made no mention of Lollesgaard or Awale.
"MINUSMA strongly condemns this terrorist act which aimed to paralyse the mission's operations in this part of Mali," it said.
"Mines in Mali indiscriminately affect United Nations The attack came a day ahead of the International Day of United Nations Peacekeepers when member states and non-governmental organisations hold events to honour fallen troops.
A Bangladeshi peacekeeper was shot dead and another wounded in Mali's capital, Bamako, on Tuesday, although the circumstances remain unclear and it has not been attributed by the UN to militants.
Malian security sources first suggested that the soldiers were targeted by "unidentified armed men" but that account was thrown into doubt by an initial inspection of the UN vehicle.
"We have launched an investigation to find out what exactly happened since, on the face of it, there are no bullet holes, just traces of blood, in the vehicle," a source later clarified.
No group has claimed responsibility for the attacks, but they come at a time of strained relations between the government and MINUSMA, which has complained that its impartiality has been "regularly called into question".
