U.S. is assessing who’s responsible for Ukraine dam explosion

The United States is assessing who’s responsible for the explosion of a dam in Russian-occupied Ukraine. The National Security Council’s John Kirby says the explosion will have long-lasting consequences. And he says it’s unknown how the damage and the evacuations will affect the ongoing war. The U-S is aware of reports that Russia is responsible for the explosion, but Kirby says the U-S cannot yet say conclusively what happened.
