Wikileaks on Monday said it was preparing to release more than 100,000 documents related to the Turkish government in the wake of a failed coup in the country that left hundreds dead, thousands injured and more than 7,000 in custody.

“Get ready for a fight as we release 100k+ docs on #Turkey‘s political power structure,” the organization posted on Twitter.

Founded by Julian Assange in 2006, the Wikileaks whistle-blowing group is best known for its release of classified US diplomatic cables in 2010 that embarrassed Washington and its allies and risked undermining US diplomacy.
