Syrian technicians accompanying unknown equipment were killed in the train explosion in North Korea on April 22, according to a report in a Japanese newspaper.
A military specialist on Korean affairs revealed that the Syrian technicians were killed in the explosion in Ryongchon in the northwestern part of the country, according to the Sankei Shimbun. The specialist said the Syrians were accompanying "large equipment" and that the damage from the explosion was greatest in the portion of the train they occupied.
The source said North Korean military personnel with protective suits responded to the scene soon after the explosion and removed material only from the Syrians' section of the train.
I have no idea what to make of this. It's not encouraging though.
