Blue/red lights seen blinking over Bahawalpur, Pakistan.It was getting dark. I was driving my bike on the road situated at nearly boundary of the city.What I saw in sky were two lights. One was red and one was blue.The blue light was blinking continuously while the red one was stable. They were falling towards the ground with an unusual fast speed. I considered it a crashing plane.But then, they stopped in sky at a fixed place for 10 seconds. It was for sure a UFO now.I stopped my bike and tried to get picture but my mobile phone camera was not so good to get picture of those lights.The lights then started to move forward at the same height with a steady speed. I tried to follow them but they soon got out of my sight.
