VIENNA (AP) - The International Atomic Energy Agency has acknowledged that one of its servers has been hacked.
The U.N. nuclear watchdog commented Tuesday after a previously unknown group critical of Israel's undeclared nuclear weapons program posted contact information for more than 100 experts working for the IAEA.
A group called "Parastoo" - Farsi for a swallow bird and a common Iranian girl's name - claimed responsibility for posting the names on its website two days ago.
Israel is commonly acknowledged to possess nuclear weapons - something it neither confirms nor denies. It says Iran is secretly working on nuclear arms - something Tehran denies - and describes the Islamic republic as the greatest threat to the Mideast.
Iran and Arab countries, however, say the Jewish state's nuclear capacities pose the greatest menace.
