Switzerland is suspending approvals to replace three of its nuclear power stations, the country's energy minister says.
The operator of Fukushima Daiichi's number 2 reactor says water levels are nearly empty.
Jiji is reporting that the fuel rods have been left fully exposed at the comlpex's number 2 reactor as levels of water coolant have fallen.
If the fuel rods were to melt down, the risk of damage to the reactor vessel would be greater, increasing the risk of a radioactive leak.
Jiji reports the operator has started injecting sea water into the reactor to cover the rods.
To clarify, the operator is plant-owner Tepco.
@borrrden: water is being "reinjected", due to the water originally covering the fuel rods having evaporated.
Russia is ready to being supplying liquefied gas to Japan from Sakhalin, the Russian territory island just north of Japan, according to Deputy Prime Minister Sergei Ivanvov. The gas will help replenish electrical power.
Qatari firms Rasgas and Qatargas are also in talks on how they can boost supplies to Japan, having been instructed by the energy ministry to see how they can help, Rasgas managing director Hamad Rashid Al Mohannadi says.
Tepco has confirmed those reports regarding the fuel rod at Daiichi's no.2 reactor, saying it has restarted pouring water into the reactor after the fuel rod was exposed by dropping water levels.
More on Tepco's comments - it says the entire fuel rod may have been exposed at one point.
Tepco says parts of the fuel rods have been damaged.
Thanks everyone for all your comments - we're trying to publish as many of them as we can, but sheer volume is making this impossible.
