The latest developments in the conflict between Russia and Ukraine. All times EDT:

4:02 a.m.: An adviser to the mayor of Mariupol, Ukraine, says that Russia’s use of “filtration camp” detention centers has turned the city into a “concentration camp,” Al Jazeera reports. 

3:07 a.m.: The Pentagon says there are no indications Belarus plans to get involved in the conflict in Ukraine, Al Jazeera reports.

2:04 a.m.: CNN reports that the Pentagon denied news reports saying the U.S. provided intelligence that helped Ukraine sink the Russian warship Moskva.

“We did not provide Ukraine with specific targeting information for the Moskva,” Pentagon press secretary John Kirby said in a statement Thursday. “We were not involved in the Ukrainians’ decision to strike the ship or in the operation they carried out. We had no prior knowledge of Ukraine’s intent to target the ship.”

1:02 a.m.: The latest intelligence update from the U.K.’s defense ministry says Russian efforts to complete the capture of Mariupol, including its Azovstal steel plant, are likely linked to Russia’s plans to celebrate Victory Day on May 9. Victory Day marks the Soviet Union’s 1945 victory over Nazi Germany. Putin, the update says, wants to have a symbolic success in Ukraine.

12:02 a.m.: The Washington Post reports that the western Ukraine city of Ivan-Frankivsk is warning its residents about possible shelling ahead of Russia’s May 9 Victory Day celebration.

Russia uses Victory Day to celebrate the Soviet Union’s victory over Nazi Germany; it’s a traditional celebration of national pride. Leaders in Ivano-Frankivsk fear that this year it’ll lead to increased Russian attacks. They’re telling residents to evacuate or to stay inside, and they’ve canceled all public events, the Post reports.
