The Israel Defense Forces (IDF) said 21 of its reserve soldiers were killed in an attack in Gaza on Monday, the deadliest single incident that the military has suffered since its ground offensive in the enclave began.
At around 4 p.m., a Hamas militant fired a rocket-propelled grenade at a tank as the reservists were preparing to demolish a pair of two-story buildings, Israeli military spokesperson Rear Adm. Daniel Hagari said in a statement. The blast triggered explosives which had been set inside the buildings for the demolitions, causing both structures to collapse on the troops, Hagari said.
On Tuesday morning, Israeli Prime Minister Benjamin Netanyahu announced that the IDF had launched an inquiry into the incident, calling it “one of the most difficult days since the outbreak of the war.”
