TOKYO (Reuters) - Following are main developments after a massive earthquake and tsunami devastated northeast Japan and crippled a nuclear power station, raising the risk of uncontrolled radiation.
* Nuclear plant still emitting radiation but source unclear, says IAEA. The UN atomic watchdog says Japan has not given some information relating to one reactor.
* Smoke and steam seen rising from two of the most threatening reactors, No.2 and No.3, denting hopes of immediate progress in bringing them under control.
* Core of reactor No. 1 also a worry with temperature touching 380-390 Celsius (715-735 Fahrenheit), plant operator says. Reactor built to run at a temperature of 302 C (575 F).
* Engineers have re-established power cables to all six reactors and have started a pump at one of them to cool overheating fuel rods. Lighting had been restored at one of the control rooms, local media said.
- The World Health Organisation says the detection of radiation in food is a more serious problem than first expected, and food contamination is not a localised problem. It says, however, there is no evidence of contaminated food from Fukushima reaching other countries.
- Plant operator TEPCO says a small trace of radiation had been found in the Pacific nearby, but officials stressed the levels were minute and posed no immediate danger.
- China and South Korea say they will toughen radioactivity tests on imports of Japanese food, and Japan tells four prefectures near the nuclear plant to halt shipments of spinach.
- Government also bans milk shipments from Fukushima province.
- Government says Japanese food produced outside the nuclear crisis zone is safe.
- Official death toll from earthquake and tsunami exceeds 9,000, Kyodo news agency reports national police as saying.
- The earthquake and tsunami will depress growth briefly before reconstruction kicks off and gives the beleaguered economy a boost, the World Bank says in a report.
