Heavy fighting is ongoing in the Gaza Strip after a combined Hamas-Islamic Jihad force attacked IDF troops dealing with terror tunnels in the Khan Younes-Rafah sector, less than three hours after an agreed 72-hour truce went into effect at 8 p.m. Friday morning. The IDF responded with artillery shelling of Rafah. The Palestinians report five dead. Red alerts of fire from Gaza also sent people running for shelter in the Eshkol and Kerem Shalom border communities. Israel has closed the Kerem Shalom crossing.
