Japan's nuclear crisis deepens, China expresses 'shock'

TOKYO (Reuters) - Japan's nuclear crisis escalated to its worst level since a massive earthquake and tsunami crippled the Fukushima plant more than two years ago, with the country's nuclear watchdog saying it feared more storage tanks were leaking contaminated water.

The U.N.'s International Atomic Energy Agency (IAEA) said on Wednesday it viewed the situation at Fukushima "seriously" and was ready to help if called upon, while nearby China said it was "shocked" to hear contaminated water was still leaking from the plant, and urged Japan to provide information "in a timely, thorough and accurate way".
