Fear grows inside Shifa

"Shelling and explosions never stopped," said Islam Mattar, one of thousands sheltering at the hospital in Shifa. "Children here are terrified from the constant sound of explosions and the scenes they are watching." The Health Ministry told Al Jazeera there are still 1,500 patients at Shifa, along with 1,500 medical personnel and between 15,000 and 20,000 people seeking shelter.

Thousands have fled Shifa and other hospitals that have come under attack, but physicians said it's impossible for everyone to get out. "We cannot evacuate ourselves and (leave) these people inside," a Doctors Without Borders surgeon at Shifa, Mohammed Obeid, was quoted as saying by the organization.
