Gaza (CNN)Dr. Ghassan Abu-Sitta peers through his black-rimmed glasses at an X-ray. "Not very good," he quips. "See how the pieces are?" he says to hospital staff, pointing at the fuzzy image.
He's treated thousands. The surgeon who keeps returning to Gaza
He leans over to cut his patient's bandages, letting out a sigh. Infection is inevitable, he says, in these "high-energy devitalizing injuries," his way of describing the damage done by Israeli sniper bullets to the human body.
Eighteen-year-old Maddah is just one of many patients Abu-Sitta has treated since Palestinians began a series of protests known as the "Great March of Return." Confrontations between Israeli troops and the protesters worsened Monday as tensions soared over the United States' relocation of its embassy in Israel from Tel Aviv to Jerusalem.
Maddah, propping himself up in bed, looks warily at the doctor, not understanding his explanation in English to the staff at Gaza's Al-Awda hospital. Maddah was shot on March 30, when the Great March of Return began.
Bandages wrap around Maddah's lower leg, which bristles with external fixation pins. As Abu-Sitta lifts his leg, Maddah winces in pain.
