The latest is that we do not know for certain if the explosion was the direct result of a carbomb. We do know that 5 are dead, 20 injured. We also know that it was not something that was directed at the military or other Western agency. It apparently was an explosion of (4) shops which all contained gun powder. Like I said, it could still have been an IED or carbomb that started it but the likihood of that is slim right now. See, the people here use open flames for cooking and they drink chai tea like we do our favorite Starbuck's drink. The present news we're getting is that it is likely one of these open flames warming someone's morning chai that caused the explosion. Apparently there was enough gun powder amoungst the (4) shops to do some damage though.
We're still in a lockdown mode until everything clears but it's less of a concern right now.
