The article says an unknown group called "Soldiers in Tshirts" claimed responsibility and said that army snipers shot down the drones. But, the group didn't respond to interview requests and firefighters at the scene said it was a gas tank explosion at an apartment building.

The burn marks on the building look like a few stories tall and a few apartments wide. If it was an aerial explosion is seemed like a pretty big one.

Even if not real, half of the people at HN could probably pull off the real thing or far worse -- fortunately the good people here are mainly rational and peaceful, but the rest of humanity isn't always so. I can't help but feel that some nasty bottle has just been uncorked.
