Ukraine has reportedly attacked Russian soil for the first time using a U.S.-made artillery system. This comes just days after the Biden administration gave Ukraine the green light to carry out such attacks despite warnings from Russia.

Meanwhile, Ukrainian President Volodymyr Zelensky is criticizing Biden for deciding not to attend an upcoming peace summit in Switzerland. Vice President Kamala Harris will attend instead. Biden, however, is expected to meet with Zelensky this week in Normandy, France, and again at the G7 summit in Italy.
