Two technicians were injured as a result of the explosion at the Florennes air base in Belgium and were treated on the spot, Sudinfo reported. They suffered hearing problems, not burns.
A fire broke out at around 14:10 local time [12:00 GMT], the military's press service said in a statement. A second aircraft suffered "collateral damage," military sources added, without specifying the extent of the damage.
As the media specified, firefighters have been deployed to the site to contain the incident.
