text:  A friend of mine said, cool, what's that? What's that over there? I turned my head to see. And then I heard a buzzing, like an F-35, but it was only maybe 30 meters above sea level. So it was strange. And then I saw a red and orange blast. I felt this heat, a blowback. One man was killed and several people injured. The drone hit just a block from the U.S. Embassy branch office and shattered windows for several blocks. And who claims responsibility for the attack?
