Ukraine is reeling from the most recent wave of Russian drone and missile strikes Thursday that killed at least 11 people and triggered emergency power outages in 10 regions of the country.
President Volodymyr Zelenskyy called for more sanctions on Russia in his nightly video address, and for a tribunal to address Russian war crimes.
The attacks came a day after Ukraine's Western allies pledged to send the country battle tanks, opening up a new front in the types of weapons they are willing to provide in the fight against Russian forces.
