Russia attacks Ukraine

Russian President Vladimir Putin announced a military operation in Ukraine early Thursday.
Ukraine’s Interior Ministry said Russia’s “invasion has begun,” with reports of troops crossing the border from multiple directions, and explosions in multiple cities including the capital Kyiv.
Ukraine’s President Volodymyr Zelensky introduced martial law across the country on Thursday, urging citizens to remain calm. Earlier, he said he had tried to call Putin on Wednesday but was unsuccessful.
