----------------------------------------
An explosion was heard at 6:10 a.m. Tuesday at a damaged reactor at the Fukushima Daiichi nuclear complex, the Japanese nuclear safety agency said.

Officials said earlier that four out of five pumps being used to flood the unit 2 reactor had failed and that the other pump had briefly stopped working, hastening the meltdown of fuel rods that at one point were fully exposed. Two explosions occurred in other reactors at the complex, one on Monday and one on Saturday.
