Ukraine Claims 90% Control of Kupiansk

Ukraine says it controls almost 90% of the town of Kupiansk, which is very important because it's a key place for trains.

The Ukrainian leader, Volodymyr Zelenskyy, even visited the town last week.

But Russia says Ukraine's attempts to take the town haven't worked.

Both sides are fighting over land, and Russia says it has taken more land this year than last year.

The town has been badly damaged in the fighting.

The United States is trying to help Ukraine, but there's no agreement yet on what land Ukraine might give up to end the war.
