What information is slowly being verified and clarified is genuinely horrifying.
In the North Korean city of Ryongchon, home to 130 thousand people, an explosion is still burning. 8 thousand homes are damaged or flattened.

North Korea has asked for help from the UN.
The Red Cross is mobilizing.
Chinese medical personnel on the border were told yesterday to get ready to help thousands of injured.
The latest reports are that border hospitals have seen no victims.
They have not yet begun to count the dead, the South Korean government says thousands, the British embassy in SK says hundreds, the Red Cross says 54.

Initially it was believed two trains loaded with gas and petroleum products collided.
Now officials are saying an electric cable fell on two trains loaded with dynamite in the crowded and busy rail station.
There are reports it was two wagons loaded with dynamite.

In 1917 something similar happened in Halifax, Canada. Instead of two trains, (or wagons?) it was 2 ships. The explosion was catastrophic and remains the largest man-made explosion until the atomic age. Is this explosion in North Korea going to be the second?
