US President Joe Biden requested Russia to stop its military activities at a Ukrainian nuclear power plant and allow emergency services. Biden joined Ukrainian President Volodymyr Zelensky in urging Russia to stop its military exercises in the area and allow firefighters and emergency responders to access the site.

Russian troops attacked the nuclear plant early Friday, and a live feed showed blasts lighting up the night sky and sending up dozens of smoke. A senior US official said that the latest information shows no signs of high radiation levels, and we are closely monitoring it. US Energy Secretary Jennifer Granholm said on Twitter that she had spoken with her Ukrainian counterpart. The site’s reactors are protected by solid containment structures and safely shut down.
