The world mourns for all who died and will die in this terrorist attack. Even though the death toll is nothing like 9.11, everyone understands that all terrorist attacks are same and ultimately lead to death of innocent people. We mourn those who died in terrorist attacks and those who die because of nationalists who wake up right after the onslaught. They are all victims of terror, the plague of the 20’Th and 21'st centuries.
