The operation, which started late Thursday, killed several people, the first victim being a 3 month-old baby boy, Fares Al-Tarabeen. His body arrived at Shifa hospital. He was still wearing his diapers.

Doctors at Abu Yousef al-Najjar hospital told MEE that scores of people were brought to hospital after breathing white poisonous gas. The patients were not able to breath and doctors were unable to treat, not knowing what kind of gas was used. People who breathed the gas screamed uncontrollably and were difficult to restrain by hospital staff. The Palestinian health ministry appealed to international groups to help deal with the crisis and help in identifying the kind of gas being used in first hour of ground invasion.
