Tonight on PBS News Weekend, Ukrainian President Volota Mer Zelenskyy says he won't give up any territory to Russia after President Trump suggests a land swap to end the war.

Then history is made as a woman umpires a regular season game for the first time in Major League Baseball's nearly 150 year history.

And scientists in South Africa are making endangered rhinos horns radioactive to save them from poaching.

You can't take that horn anywhere. It is radioactive.

You can't take it through any airport, any harbour, any customs office.

I'm telling you this could be tonight in Ukraine where President Volota

Mazzolensky has flatly rejected President Trump's suggestion that a peace deal between Ukraine

and Russia might include

the two nations swapping territory. In advance of Mr. Trump's summit with Russian President

Vladimir Putin in Alaska next week, Zelensky said he wouldn't agree to anything that comes

out of any meeting that leaves his nation on the sidelines. He accused Russia of stalling.

Russia started it and is dragging it out, ignoring all deadlines, and that is the problem, not something else. The answer to the Ukrainian territorial question already is in the

Constitution of Ukraine. No one will deviate from this, and no one will be able to.

Ukrainians will not gift their land to the occupier.

Mr. Trump had set a Friday deadline for Russia to end the war or face additional sanctions,

but that deadline came and went without any new penalties.

And the war in Gaza, growing outrage over Israel's plan to take control of Gaza City,

including among Israelis.

Thousands rallied outside the Israeli military headquarters in Tel Aviv.

Family members of hostages, as well as anti-government protesters, demanded that Prime Minister Benjamin Netanyahu make a deal with Hamas to release all of the hostages still in Gaza.

This, as attempts to provide aid in Gaza, are increasingly troubled,
