More than 340 children in the Kurdish south-east of Turkey have been given long prison sentences in the past three years.
Most of them were detained for taking part in anti-government protests, under a law banning any show of support for the outlawed Kurdish Workers' Party, or PKK.
The government says it knows the law, which requires a minimum five-year sentence, is too harsh, but it has yet to change it.
