The head of the International Atomic Energy Agency said he was “deeply concerned” with the situation at the power plant and was in contact with Ukrainian authorities.
FIGHTING RAGES, SANCTIONS MOUNT
On Thursday, Russia and Ukraine negotiators agreed to the need for humanitarian corridors to help civilians escape and to deliver medicines and food to the areas where fighting was the fiercest.
Ukrainian presidential adviser Mykhailo Podolyak said a temporary halt to fighting in select locations was also possible.
The negotiators will meet again next week, the Belarusian state news agency Belta quoted Podolyak as saying.
Only one Ukrainian city, the southern port of Kherson, has fallen to Russian forces since the invasion was launched on Feb. 24, but Russian forces continue to surround and attack other cities.
Mariupol, the main port on the Sea of Azov, was surrounded and under heavy bombardment. Water and power was cut off, and officials say they cannot evacuate the wounded.
Video posted on Twitter from Mariupol, and verified by Reuters, showed parked vehicles burning while non-stop firing reverberated around surrounding apartment blocks.
The northeastern city of Kharkiv has been under attack since the start of the invasion, but defenders are holding out in the heavily shelled city.
While no major assault has been launched on Kyiv, the capital has been shelled, and Russian forces unleashed devastating firepower to break resistance in the outlying town of Borodyanka.
In Washington, a U.S. defense official said Russian troops were still 25 km (16 miles) from Kyiv city centre. Earlier on Thursday, the British Ministry of Defence said a huge Russia convoy rumbling southwards toward Kyiv, was advancing slowly, partly due to resistance, but also due to logistical issues.
The United States and Britain announced sanctions on more Russian oligarchs on Thursday, following on from EU measures, as they ratcheted up the pressure on the Kremlin.
More companies including Alphabet Inc’s Google, footwear giant Nike and Swedish home furnishing firm IKEA shut down or reduced operations in Russia as trade restrictions and supply constraints added to political pressure.
Sanctions have “had a profound impact already,” Biden said.
Russia calls its actions in Ukraine a “special operation” that is not designed to occupy territory but to topple the democratically elected government, destroy its neighbour’s military capabilities and capture what it regards as dangerous nationalists. It denies targeting civilians.
Russian human rights activist and former world chess champion Garry Kasparov called on Western countries to eject Russia from the global police agency Interpol, and impose a no-fly zone over Ukraine.
“Russia should be thrown back into the Stone Age to make sure that the oil and gas industry and any other sensitive industries that are vital for survival of the regime cannot function without Western technological support,” Kasparov said.
