There have been conflicting death tolls as Israel's operation unfolded across multiple cities. The IDF said yesterday that nine militants had been killed, five in Jenin and Tulkarm, and four in al-Faraa refugee camp. The Palestinian health ministry said on Thursday that 12 people had been killed in IDF attacks so far. UN Secretary General Antonio Guterres has called on Israel to immediately halt its operation, saying it was "fuelling an already explosive situation". He urged Israeli forces to "exercise maximum restraint and use lethal force only when it is strictly unavoidable". The IDF said the five Palestinians were killed after "exchanges of fire" in Tulkarm.
