well i wasn't in Lebanon at that time ... I was in Egypt (Alexendria) and as I recall i was having an exam in Anesthesiology and was coming back to the hotel when i heared the explosion

(just kidding) ... i just saw my friend and told me about the incident ... so i rushed to the hotel to watch the news on TV and i was shocked ... and i remember trying to call my family here and wasn't able for several hours ...
Thank You ...
