The explosion at a liquefied petroleum gas plant took place shortly after an anonymous bomb threat, police said. It was not clear if there were any casualties.
Authorities said a fire touched off by the blast at the plant, where cooking gas canisters were filled, was under control, private NTV television reported.
The two earlier explosions rocked inexpensive hotels, which often host tourists from former Soviet republics, at around 2 a.m., police said.
these explosions do not seem to have the class that an AQ attack tends to have (Timing, shock, loss of life). I suspect that this might be kurds or some other low life group wanna be's
