“Open! Open!” the crowd chanted. Excited young men clambered on top of that first gate, which had been broken open, and began bouncing up and down on it, trying to knock it off its hinges.All of a sudden, an invisible, noxious gas began to pour into the crowd from the Hungarian side. In a panic, the people nearest the gate began to scramble backward, pushing people aside as they flailed, tears streaming from their eyes. Children grabbed for their parents. Some tossed oranges and apples they had been carrying back at the riot police, ineffectually. People ran into one another, tripped, fell.
