U.S. shows growing alarm over Japan nuclear crisis

WASHINGTON (Reuters) – The United States showed increasing alarm about Japan's nuclear crisis on Wednesday and urged its citizens to stay clear of an earthquake-crippled power plant, going further in its warnings than Japan itself.

The State Department said the United States has chartered aircraft to help Americans leave Japan and had authorized the voluntary departure of family members of diplomatic staff in Tokyo, Nagoya and Yokohama -- about 600 people. yahoo/Reuters
