The Lulz Security group of hackers said in a Tweet that it had launched an attack on the public website of the U.S. Central Intelligence Agency.
The site, www.cia.gov, was unavailable for a few minutes on Wednesday evening, immediately after the group announced the attack via Twitter.
“We are looking into these reports,” a CIA spokeswoman said.
