Editor's note: Tune in to AC360° tonight beginning at 10pm ET to get the latest from Anderson Cooper and CNN's team of correspondents and producers on the ground in Japan. We'll also have the latest out of Libya.
Workers in Japan are scrambling to cool the damaged reactors at Fukushima Daiichi nuclear plant. After deploying water cannons and helicopters to dump water on the facility, officials are now working to restore power at the site.
Engineers have an emergency diesel generator running at the No. 6 reactor, which is also supplying power to reactor No. 5. There's also been confusing reports on efforts to install a cable to restore power to reactor No. 2. Citing Japanese authorities, the International Atomic Energy Agency (IAEA) said the power cord reached the unit and would be connected after the spraying of water on the No. 3 reactor was completed.
But a Tokyo Electric Power Company (TEPCO)spokesman said the electrical line is not connected, though they hoped it would be by Friday night.
Meanwhile, we're getting new details on the health of those workers risking their lives at the plant. According to the IAEA, at least 20 people have fallen ill because of possible radiation contamination. The agency also reports 19 people were injured and two are missing at the plant.
There are also breaking developments on Libya. The U.N. Security Council voted tonight to impose "all necessary measures", including a no-fly zone, as forces loyal to Libyan leader Moammar Gadhafi approach a key rebel stronghold.
"Today the security council has responded to the Libyan people's cry for help," U.S. Ambassador to the U.N. Susan Rice said.
The resolution was approved with 10 votes, including the U.S. There were no opposing votes of the 15-member council, but Russia, China, Germany, India and Brazil abstained.
It's unclear when the international community might take military action in Libya.
A defiant Gadhafi addressed his country on the radio earlier today.
"Let the whole world launch war against us. Bomb us even with atomic bombs. This is our country. We will never give up."
Anderson Cooper goes beyond the headlines to tell stories from many points of view, so you can make up your own mind about the news. Tune in weeknights at 8 and 10 ET on CNN.
