President Volodymyr Zelenskiy landed in Saudi Arabia on Monday to meet Crown Prince Mohammed bin Salman, a day before talks between Ukrainian and U.S. officials that Washington expects to deliver substantial progress towards ending the war with Russia.

Ukraine launched its largest drone attack on Russia as U.S. officials were meeting a Ukrainian delegation in Saudi Arabia to secure a peace deal.

The United States, Ukraine and Russia have very different ideas about what a potential agreement to end, or at least pause, the war should look like.
