Russia-Ukraine live updates: 'Powerful explosions' heard in Russian city of Belgorod
There were no reports of casualties or damage.
Russian President Vladimir Putin's "special military operation" into neighboring Ukraine began on Feb. 24, with Russian forces invading from Belarus, to the north, and Russia, to the east. Ukrainian troops have offered "stiff resistance," according to U.S. officials.
The Russian military last month launched a full-scale ground offensive in eastern Ukraine's disputed Donbas region, attempting to capture the strategic port city of Mariupol and to secure a coastal corridor to the Moscow-annexed Crimean Peninsula.

US Embassy staff back in Ukraine for 1st time in months
U.S. Embassy staff returned to Ukraine for the day on Monday, marking the first trip back in the country since February.
"We expect to continue to do day trips for the next week or two and we very much hope that the conditions will permit us to go back to Kyiv by the end of the month," Kristina Kvien, the U.S. chargé d'affaires to Ukraine, said in a statement.
Kvien said, "The message to Russia is: you failed -- Ukraine is still standing, the government is still functioning and we are going back to Lviv first and then Kyiv to help the government."
Kvien continued, "We are listening to the security professionals and when they tell us we can go back we go back. And while we are eager to do so we also want to make sure we are listening to the experts. So, the fact that we are here in Ukraine means that the security officials just said that it is ok and safe to meet here in Lviv and hopefully we will get the clearance to go back to Kyiv."

1st group of civilians leave Mariupol steel plant
Dozens of civilians trapped for weeks inside a steel plant in the devastated Ukrainian city of Mariupol were expected to reach Zaporizhzhia on Monday, according to Ukrainian President Volodymyr Zelenskyy.
In a statement posted to Twitter on Sunday, Zelenskyy said a first group of about 100 people were already en route to the Ukrainian government-controlled city, about 140 miles northwest of Mariupol.
"Tomorrow we'll meet them in Zaporizhzhia," Zelenskyy tweeted. "Grateful to our team!"
Many more civilians remain trapped at the sprawling Azovstal Iron and Steel Works plant in Mariupol -- the last holdout of Ukrainian resistance to Russia's bombardment of the strategic southeastern port city -- which Russian forces resumed shelling overnight.
"Today, for the first time in all the days of the war, this vitally needed green corridor has started working," Zelenskyy said Sunday in his nightly address.
