Israeli forces have launched an overnight raid on the al-Shifa hospital in Gaza, with reports of tanks and heavy gunfire at the facility.
An Israel Defense Forces spokesperson said the IDF was carrying out a "high precision operation in limited areas" of the hospital.
The IDF said "senior Hamas terrorists have regrouped" inside the hospital and are using it to launch attacks.
Eyewitnesses described a state of panic inside the complex in Gaza City.
In a recorded call with his brother posted on a WhatsApp group, one man said: "Tanks are surrounding us. We are hiding inside the tent. We hear tank fire in the vicinity of the compound."
