BAMAKO (AFP) - Militants opened fire on two Bangladeshi United Nations peacekeepers in Mali's capital Bamako on Monday, killing one and wounding the other, security sources said.

"Armed men that we have not yet identified shot at two peacekeepers who were on board a UN vehicle on Monday night. One of them was killed and the other seriously wounded," a Malian security source told AFP.

"We are seeking clarification and details. This has to be viewed as a terrorist act. The perpetrators are the enemies of peace," the source added.

A source from MINUSMA, the UN's peacekeeping mission in Mali, told AFP the two UN soldiers were Bangladeshi.

He said the peacekeepers had been travelling from Bamako airport towards the south of the city when they were shot at by assailants from a car.
