Sirens and loud thuds and flashes of orange light lit the sky in the eastern Gaza strip as Israeli gunboats fired shells and tracer fire, while artillery and helicopters fired over the border, witnesses on both sides of the border said.
Gaza residents and medical officials reported heavy shelling along the eastern borders from the southern town of Rafah up to the north of the enclave.
Shells landed by the al-Wafa rehabilitation hospital east of Shejaia, an eastern suburb of Gaza.
Basman Alashi, head of the hospital, said: "We were not able to evacuate all the patients, the staff can barely evacuate themselves at this point It's a desperate situation.
"The hospital has been hit many times."
