The attack happened on Monday in Minbya, in the country’s northwestern Rakhine state, where the military has been fighting with the Buddhist insurgent group Arakan Army.
The UN’s Myanmar mission named the driver as Pyae Sone Win Maung, saying it was “deeply saddened” to confirm his death.
UN Secretary-General António Guterres “strongly condemns the 20 April attack,” his spokesman said in a statement.
“The Secretary-General expresses his condolences to the family of the deceased and wishes a swift recovery to the injured. He calls for a full and transparent investigation into the incident and for the perpetrators to be brought to justice.”
