Newly released video of the Tsunami and the search for survivors in Japan

A new explosion rocked Japan's Fukushima Daiichi nuclear power complex on Monday, sending a plume of smoke into the air.

Reuters reports from Tokyo: Japanese authorities have been working desperately to avert a meltdown, compounding a nuclear catastrophe caused by Friday's massive quake and tsunami.

The core container was intact, Jiji news agency said, quoting the plant operator, Tokyo Electric Power Co, but the local government warned those still in the 20-km (13-mile) evacuation zone to stay indoors. Kyodo news agency quoted TEPCO as saying workers were injured in latest explosion.
