Fox News contributor Dan Hoffman joins'Fox & Friends' to discuss Ukraine's claims that Russia has violated the partial ceasefire deal and Putin's threat to Trump over his effort to acquire Greenland. Two people were killed and 35 others were injured after a Russian drone attack struck a military hospital and shopping center in Ukraine late Saturday night, Ukrainian officials say. Regional Gov. Oleh Syniehubov condemned the attack on Kharkiv in a statement on Sunday, saying a 67-year-old man and a 70-year-old woman were killed. The attack comes as Russia's aggression in Ukraine shows no signs of stopping despite efforts by President Donald Trump's administration to speed along peace talks. Ukraine says that many of the casualties were servicemen undergoing treatment at the military hospital.

Russia has suffered multiple diplomatic and judicial blows during the past week over its war on Ukraine, despite President Vladimir Putin's high-profile visits to North Korea and Vietnam and Moscow's claims that it is founding a "Eurasian security architecture that will replace the discredited Euro-Atlantic security arrangements". Putin signed a "comprehensive strategic treaty" with North Korean leader Kim Jong Un on June 19, incorporating what he said was a defensive alliance. South Korea's government condemned the agreement. Its national security adviser, Chang Ho-jin, declared that Seoul would reconsider lifting a ban on arms supplies directly to Ukraine. Until now, South Korea has only sold weapons to Ukraine's allies.

Russian drone strikes near a nuclear power plant in western Ukraine this week have revived anxiety among Ukrainian officials and civilians over one of the most oppressive hardships of the war: a winter assault on their nation's energy grid. The strikes Wednesday, which landed near the Khmelnytsky nuclear facility, drew an angry response from President Volodymyr Zelenskyy of Ukraine, who said it was "highly likely" that the power plant was the target. They also prompted another warning from the head of the United Nations' nuclear watchdog agency about the precarious nuclear safety situation in Ukraine. Zelenskyy vowed Wednesday night that Ukraine would hit back at targets inside Russia if Moscow tried once again to plunge his nation into cold and darkness.
