My friend and i were watching the sky from the balcony,suddenly we noticed a kind of flying object in the sky .While the distance was lower than an altitude of a plane ,it was illuminated by white lights and its surface was grey.Its shape was amazingly like a cone that its vertex was much more brighter and it was moving straightly to the southeast and was nearing to the ground. we both were frightened then i just picked up my phone and took some photes that i have attached them below. after 15 minutes the light decreased and finally we lost the whole sight.
