Fukushima, Japan:
The Japanese fire department released a video on Wednesday showing firefighters in protective suits spraying water into the troubled No. 3 reactor at the stricken Fukushima Dai-ichi nuclear plant.
The video which was filmed last Friday shows members of the elite "Hyper Rescue" team of the Tokyo fire Department, during the first water injection mission.
The team injected 60 tonnes of seawater into the reactor.
Last Friday, exactly a week after the earthquake fed tsunami had devastated the Fukushima plant, Japan's nuclear safety agency had raised the rating of the country's nuclear accident from 4 to 5 on a 7-level international scale.
