^The video was apparently taken soon after the building collapsed as some videos taken later showed that the area was cordoned off.
A tenement building around 50 y.o. was reduced into rubbles in Tokwawan (not Hung Hom), Hong Kong yesterday, killing several residents and leaving some missing. The tragedy was really horrible as it happened on the main street of this old area. When I was testing the GXR, I was two blocks away from this scene. I walked under many of like buildings then.
An AFP report quoted a witness as saying, "I saw bits and pieces of earth and tiles sliding down the wall at the beginning. A woman was trying to climb out through the window. About 15 seconds later, the building fell like dominoes."
