Japan declares emergency at nuclear site; no radiation leak

TOKYO - Japan started to evacuate thousands of residents from an area around a nuclear reactor after damage caused by a powerful earthquake raised fears of a radiation leak, although officials said there was no sign of leakage at present.

Work has begun on restoring the reactor's cooling function, Jiji news agency quoted the Trade Ministry as saying, while Kyodo news agency quoted Fukushima prefecture as saying that water levels at the reactor were not at critical levels.
