What started as a peaceful demonstration turned ugly at the end. Why? I do not know as I was too far from the front to see what was happening. All I knew was that suddenly the police started spraying tear gas from their vehicle. People started running away. I had to run too. Managed to escape that one but there were many others. Although I wasn't hit directly, my eyes felt the sting. At one time I had difficulty opening them, such was the effect. A few nice strangers gave me salt while I had with me water. That helped.
