I live far away from it, but I heard this massive BOOM! just before 4AM. Then it was followed by several more. It sounded too sudden to be thunder, so I got up and checked the windows. --Totally clear sky! Stars and everything. Sensing something wasn't right, I turned on the news and watched it until past 4:45 AM thinking that something's got to be very wrong... but by 4:45, the news didn't say anything.
Even though I could still hear some booming in the distance (explosions were still going on close to an hour later, I guess) I went back to bed and tried to fall asleep listening to sirens wailing. Then, due to the sirens, I got up again and checked the news websites for news... nothing. So I closed my window and went back to bed.
