IRNA � Washington said on Friday that it has put the name of 10 Iranian individuals and one institute on its sanctions list, alleging they have been involved in cyber attacks against the US.

The Iranian individuals and institute have been involved in targeting hundreds of universities, the US Treasury Department claimed.

The sanctions block any transactions with those named and freeze any assets they may have under US jurisdiction, it added.

It is not the first time the United States claims it has been under cyber attack.

Last week, the administration accused the Russian government of cyber attacks stretching back at least two years that targeted the US power grid. Washington imposed new sanctions on 19 Russians and five groups, including Moscow�s intelligence services, for meddling in the 2016 US presidential election and other cyber attacks.
