A second explosion has hit the nuclear plant in Japan that was damaged in Friday's earthquake, but officials said it had resisted the blast. TV footage showed smoke rising from Fukushima plant's reactor 3, a day after an explosion hit reactor 1.
An estimated 170,000 people have been evacuated from the area around a quake-damaged nuclear power station in north-east Japan that was hit by an explosion, the UN atomic watchdog says.
A mammoth relief mission is swinging into action in north-east Japan, a day after it was struck by a devastating tsunami, claiming hundreds of lives. Whole villages have been washed away and at least one town has been largely destroyed.
