Protesters practice shield formation before clashes

Video obtained by Reuters showed anti-coup protesters practicing retreating and advancing with the makeshift shields, one of an increasing number of ways protesters have used to protect themselves from security forces.

Protesters have also used longstanding superstitions like the idea that it is bad luck to walk under women's clothing to stop police from charging at them.

Security forces have opened fire with stun grenades, rubber bullets and live rounds since the start of the coup in February, causing the deaths of more than 50 protesters, according to the United Nations.
