The U.S. Army's public website was temporarily shut down on Monday to resolve a hack from the Syrian Electronic Army.

The Army's website suddenly displayed messages like "You have been hacked" and "Your commanders admit they are training the people they have sent you to die fighting," according to NBC News.

The Army confirmed the website breach, according to CNN. "Today an element of the Army.mil service provider's content was compromised. After this came to our attention, the Army took appropriate preventive measures to ensure there was no breach of Army data by taking down the website temporarily," said spokesman Brig. Gen. Malcom B. Frost in a statement.

It has been clarified that the U.S. Army's website acts as an informational tool for the public and does not contain any confidential information

The Syrian Electronic Army, which has been associated with the pro-Assad group, claimed that it is responsible for the website hack on Twitter. This is not the first time that the group hacked a U.S. website—it previously attacked the websites of news organizations, Associated Press and Chicago Tribune. The AP hack caused the stock market to drop 150 points in about two minutes because the AP Twitter account indicated that the White House was under siege, according to the Washington Post.
