Twenty minutes later the calm broke when a volley of rocks and bottles began to rain down on police and protesters alike. Suddenly the air was again full of tear gas and I wiped feverishly at my eyes, trying to shoot frame after frame as figures darted in and out of the bitter fog. Protesters charged at the police screaming, “King Gyanendra is a thief, he stole our country,” and I found myself in a human pile, attempting to protect my cameras and body while being stampeded by the retreating security forces. When the air cleared, I found myself cut off from my friends.
Here.
