The governors of Hiroshima and Nagasaki, the mayor of Nagasaki and many other municipal officials protested Saturday over a U.S. subcritical nuclear test.

In a letter sent to U.S. President George W. Bush, Hiroshima Gov. Yuzan Fujita said he is angry that the United States conducted the test Friday despite repeated calls on it not to do so. He described the test as "a challenge to the international community."

Fujita also criticized the Bush administration for not ruling out a possible nuclear attack against Iran and Iraq.

Nagasaki Gov. Genjiro Kaneko and Nagasaki Mayor Itcho Ito also sent similar protest messages to the U.S. Embassy in Tokyo.
