This is crazy. They are all kids on the frontline. Aged 9 and up. Average age by the look of it is 15. Kids lie to me about their age, say 12 when they are clearly 10 years old. Most are wearing surgical masks and eyes red from teargas.

By asking a few why they are here, they say their older brothers were injured or killed by police. It's not clear if this is meant literally or not.

It's like being in a school playground. Yet every couple of minutes a shot is heard and a volley of tear gas lands and kids run away. Two or three fall breathless and other kids carry them to fresh air or an ambulance.
