Casualties were brought to Al Shifa Hospital in Gaza City on Tuesday after Israeli gunfire killed at least 17 Palestinians and wounded dozens as thousands of displaced people approached an aid distribution site of a U.S.-backed humanitarian group in central Gaza, local health authorities said. "There were grave injuries to the patients and wounded, there were injuries to the upper limbs in the upper areas of the body and also the lower limbs of the body. The condition of the injured was critical," said Palestinian doctor Mohammed Abu Salmeyah. The Israeli military said its forces fired warning shots at "suspects who were advancing in the area of Wadi Gaza and posed a threat to the troops." It added that it was aware of reports that several were injured, but argued numbers released by local health authorities did not align with the information they collected. Last week it warned Palestinians not to approach routes leading to sites of the U.S.-backed Gaza Humanitarian Foundation (GHF) between 6 p.m. and 6 a.m. local time, describing these roads as closed military zones. There was no immediate GHF comment on Tuesday's incident.
