"He is extremely happy and honoured to win this prize."

Myanmar has been in turmoil since the military seized power in a coup on 1 February coup leading to daily protests and a huge civil disobedience movement.
More than 1,000 civilians have been killed in the military crackdown, according to an advocacy group.
The anonymous photographer said in a message that he had been on the streets every day since February.

"On the ground, we stopped working with helmets marked "Press" as we realised the soldiers were targeting photographers," he said.
