"In Ryongchon Blast, Syrian engineers were killed and wounded. A wagon carrying a large cargo had a particularly heavy damage, revealed on 6th (of May, 2004) by a military news source who has great expertise on Korean matters." According to the source, "the content of the cargo is unknown. However, after the accident, N. Korean military personnels in protective suits arrived at the scene, and recovered the remains of the destroyed wagon. We strongly suspect that the accident occurred while transporting a top-secret cargo between N. Korea and Syria."
...
Syrian casualties went home via a Syrian transport plane on May 1st, which was there to pick up the cargo. All personnels involved in the transport (of Syrians), both Syrians and N. Koreans, were again wearing protective suits.

I guess the cargo wasn't oil and liquified petroleum as initially suggested in the news but discounted as very unlikely by many smart freepers!
