Pilgrims will stay the night in Mina valley, their first of two (or three) days they have to attend in worshipping, devil throwing and sacrifice slaughtering. Streets, tunnels, bridges and flyovers of Mina glitter with bright electrification, similar to any modern city of the world, eyewitnesses told the Saudi Press Agency. Given that more than two millions of pilgrims should perform the same ritual over a specific time in a limited area like Mina, the authorities have done a good job, one said. However, today's devil throwing was successfully accomplished without a single accident of stampede, thanks to the recently-implemented constructural developments at the scene "Jamarat area".
