Israel discovered a new cross-border tunnel from the Gaza Strip on Tuesday that its military said extended “dozens of metres underground” and into southern Israel.
The military said its engineers discovered the tunnel using underground sensors attached to a concrete barrier that, once completed, will run 65 kilometres (40 miles) around Gaza.
Soon after the announcement, a rocket was fired from Hamas-ruled Gaza toward Israel and intercepted by its Iron Dome anti-missile system, the military said. In response, Israeli aircraft struck a Hamas facility in southern Gaza, it added.
There were no reports of casualties on either side.
Palestinians have used underground tunnels to smuggle in all manner of commercial goods to Gaza, as well as to bring in weapons for militants from Hamas and other groups.
