IWAKI, Japan — Video footage shows an explosion at a nuclear power plant in Japan on Saturday.
The explosion at the Fukushima Dai-ichi power plant injured four workers and caused mass-evacuations, and was followed by a second explosion Monday.
The video shows the explosion sending smoke and debris shooting into the air as a building is blown apart.
At least 10,000 people have died since a magnitude-8.9 offshore quake triggered a 23-foot tsunami that struck Japan on Friday.
