Palestinians in and outside of Gaza have expressed relief over the planned four-day pause in fighting, but they fear Israel will ramp up its offensive once the cease-fire ends.

The plight of 39 premature babies at Gaza's biggest hospital, Al-Shifa, captured the world this month — and now, 31 of those infants have made it to relative safety after being evacuated from the besieged medical facility to a hospital in Rafah, near the Egyptian border, health officials told NBC News.

NBC News was given access to Gaza City on Wednesday to see the main evacuation route that thousands of Palestinians have taken to move south amid Israel’s offensive.

Israeli forces raided Gaza's Al-Shifa hospital, alleging that intelligence indicated Hamas activity there. Doctors, health officials and Hamas deny the allegations.

In the wake of the Hamas terror attack, the Israeli military’s deadly bombardment of the Gaza Strip has left a mounting death toll with graves and grief overflowing.

Israel has offered fuel and mobile incubators to Gaza’s Al-Shifa hospital as outrage grows. Doctors and health officials in Gaza say the gestures are inadequate.

Dropping a nuclear bomb on the Gaza Strip and establishing "sterile zones" that would block Palestinians from entering.

Efforts by health workers to evacuate some of Gaza’s biggest hospitals appear to be failing despite promises from Israeli forces to allow those wounded and sick to go south.

Three babies died at Gaza's largest hospital, according to the Palestinian Health Ministry, as it went out of service amid Israeli bombardment.

"We'll talk about it when it's there. We'll announce it if it's achieved," Israeli Prime Minister Benjamin Netanyahu said in an interview on "Meet the Press."

Power outages have hit the ICU and the pediatric ward at Gaza's main hospital after heavy bombardment and fighting, Palestinian health officials said.
