Tonight on PBS

PBS news weekend, the latest as Israel continues bombarding southern Gaza and orders

the leagered Palestinians to evacuate.

Then why the Arctic Ground Squirrel may hold clues for treating injuries and curing disease in humans.

And author Stephanie Land on her latest memoir class about navigating motherhood, poverty, and college.

My main motivation in talking about what it's like to live under the poverty level is so that other people

who live that experience won't feel so isolated and alone. Good evening. I'm John Yang.

Tonight Israel has ordered more evacuations in southern Gaza

and says its ground operations have expanded to include every part of the Gaza Strip.

Over a Hanyunus, Gaza's second largest city, Israel dropped leaflets declaring the area a dangerous combat zone.

That residence day was followed by heavy bombardment.

Some of those under evacuation orders have already been displaced at least once before.

The United Nations estimates that nearly 80% of the Gaza Strip's

2.3 million people have fled their homes and Gazans say they're running out of

safe places to go. There's no safe place in Gaza. We were in Zetun, it was shelled. We were in the

shaty camp, it was shelled. We moved because what can we do? We have children and all night

there's shelling so we move from area to area but there's no safety anywhere in Gaza.

In the face of the mounting death toll in Gaza, Biden administration officials have repeatedly stressed Israel's responsibility to protect civilians.

On the Sunday talk shows today, National Security Council spokesman John Kirby pointed to the

evacuation orders as evidence the message is getting through and fears that

the conflict could widen across the region were stoked by reports that a US Navy destroyer, the US-Karni, shot down a drone in self-defense in the Red Sea.

The action came during an attack claimed by Huthy rebels on commercial vessels off the coast of Yemen.
