According to reports, Iran’s supreme leader has ordered an amnesty or a reduction in prison terms for “tens of thousands” of people detained amid the nationwide protests shaking the country.

The ruling made on Sunday acknowledges the scope of the crackdown for the first time.

The decree by Ayatollah Ali Khamenei, part of a yearly pardoning the supreme leader does before the anniversary of Iran’s 1979 Islamic Revolution, comes as authorities have yet to say how many people they detained in the demonstrations.

However, there is no information about exactly who received the reported relief.

During the protests, over 19,600 people have been taken into custody, according to Human Rights Activists in Iran, a group that’s been tracking the crackdown.

At least 527 people have been killed.
