New Yorkers marked the fourth anniversary of the September 11th terrorist attacks in the United States with a solemn ceremony at the site of the fallen World Trade Center towers. New York City paid tribute to the victims of the terrorist attacks in a fourth commemoration ceremony almost identical to the three earlier ones. This year, the brothers and sisters of victims read the names in a solemn ceremony at what has become known as Ground Zero, the site of the collapsed twin towers. The ceremony paused for four separate moments of silence to observe the times when two of four hijacked airplanes struck the two towers, and the times when each tower collapsed. Bangladeshi parents of a newly wed couple who lost their lives during the attack on twin tower pledged to see the perpetrators punished.
