U.S. warns Russia "stepping up efforts" against civilians in Ukraine

What they're saying: "The Department of State has information that Russia is stepping up efforts to launch strikes against Ukraine's civilian infrastructure and government facilities in the coming days," the U.S. Embassy said in its alert.

• "The U.S. Embassy urges U.S. citizens to depart Ukraine now using privately available ground transportation options if it is safe to do so."

The big picture: Security has been bolstered in Kyiv and across Ukraine ahead of Independence Day, with officials announcing public gatherings are banned due to concerns about increased Russian airstrikes during the holiday period.

• The car bomb death of Darya Dugina, daughter of Russian ultra-nationalist Alexander Dugin, has led some nationalists in Russia to call for an escalation in the war on Ukraine after the Kremlin blamed Kyiv for the attack, which Ukrainian officials deny.

Meanwhile, the area around Zaporizhzhia Nuclear Power Station continues to be shelled, raising concerns the plant could be attacked. The European Union, U.S. and 41 other countries have demanded Russian forces withdraw from the area.
