Egypt has begun flooding the smuggling tunnels that run between the Hamas-controlled Gaza Strip and Egypt’s Sinai Peninsula. The tunnels’ destruction is among the terms of an Egyptian-brokered agreement to end Israel’s eight-day Operation Pillar of Defense, which the Jewish state launched in November 2012 after weeks of escalatory rocket and missile fire conducted by Hamas-led forces and targeted at Israeli civilians. The campaign saw Israel substantially degrade Hamas’s command and control infrastructure, as well as the Iran-backed group’s arsenal of advanced rockets. The level of Hamas rocket fire since the operation has remained at its lowest levels in roughly a decade.
