The last three hospitals still partially functioning in northern Gaza have been encircled by Israeli troops and caught amid fighting for weeks. Beleaguered staff inside struggle to treat waves of wounded, while haunted by Israeli military raids conducted against them late last year. The Kamal Adwan, al-Awda and Indonesian hospitals still have not recovered from the damage. The Associated Press gathered accounts of the raids on the three hospitals, part of a series of systematic assaults on hospitals across Gaza that have crippled the health system. Israel says Hamas uses hospitals as command and control bases, but in the cases of the three hospitals, it presented little evidence of a major Hamas presence.
