Part one of a series of emails the organization plans to release, the first batch contains nearly 300,000 emails that date from 2010 to one week before the failed coup attempt.

In a statement, WikiLeaks claims that the source of the emails "is not connected, in any way, to the elements behind the attempted coup, or to a rival political party or state."

The organization planned to release the documents later in the year, but moves its publication date forward in light of Ankara's crackdown on those supsected of being involved in the coup.

"It should be noted that emails associated with the domain are mostly used for dealing with the world, as opposed to the most sensitive internal matters," WikiLeaks said in its statement.

Ahead of the release, WikiLeaks claimed it suffered a cyberattack, possibly aimed at preventing the email from being made public.

"Our infrastructure is under attack. #TurkeyPurge #Turkey," the organization tweeted. "We are unsure of the true origin of the attack. The timing suggests a Turkish state power faction or its allies. We will prevail and publish."

These attacks have continued now that the documents have been published.

Fighting in the streets of Istanbul and Ankara last week left nearly 300 people dead and over 1,400 injured as part of the Turkish military's attempted overthrow of the govermnet of Turkish President Recep Tayyip Erdogan.

In the wake of the coup attempt, Ankara has launched an unprecendented crackdown on thousands of individuals suspected of being involved in last week's failed coup attempt, including governors, prosecutor, intelligence officers, judges, and military personnel.

Earlier on Tuesday, the Turkish government filed a formal request with Washington for the extradition of political and religious figure Fetullah Gulen, who Ankara has blamed for the coup attempt.
