Gaza/Jerusalem: The Israeli military said on Sunday it had destroyed a cross-border attack tunnel that ran from Gaza into Israel and Egypt, dug by the Hamas, the group that controls the Palestinian enclave.
Residents in Gaza said Israeli jets bombed an area east of the southern town of Rafah, by the Egyptian and Israeli borders, late on Saturday night.
Israel confirmed the attack immediately after, but gave no details until Sunday.
There was no immediate comment from Hamas or Egypt, or any reports of casualties.
Tensions have risen since President Donald Trump reversed decades of US policy on December 6 by recognising Jerusalem as Israel’s capital. Gaza militants have launched 18 cross-border rockets or mortar bombs, causing no fatalities or serious injuries in Israel, and 15 protesters and two gunmen have been killed by Israeli fire.
The attacks from Gaza, which Israel has blamed on groups not affiliated with Hamas, have drawn Israeli air strikes, usually on targets that have been evacuated.
"There are those who say the Israeli military attacks sand dunes - that is incorrect," Prime Minister Benjamin Netanyahu, addressing criticism from lawmakers who have called for a stronger armed response, told reporters after the tunnel was targeted.
Netanyahu cautioned Hamas that Israel "will respond with even greater force" if rocket strikes continue.
Israel has said Hamas, as the dominant force in Gaza, bears overall responsibility for any attacks from the enclave.
But Yoav Galant, a member of Netanyahu's security cabinet, said on Army Radio that Israel is "not looking for confrontation with Hamas". Nonetheless, he said Israel "could not abide by a situation in which Israelis are harmed by fire (from Gaza)".
Colonel Jonathan Conricus, an Israeli military spokesman, described the target hit on Saturday as 1.5 km (one mile)-lone "terror tunnel" running the Kerem Shalom border crossing into Israel, and into Egypt.
"It could also have served to transfer terrorists from the Gaza Strip into Egypt in order to attack Israeli targets from Egypt," he said.
Kerem Shalom, the main passage point for goods entering Gaza, was shut down on Saturday before the Israeli attack.
Underground tunnels are used to smuggle in all manner of commerical goods to Gaza, and to bring in weapons for fighters from Hamas and other groups.
They have also been used by Hamas to launch attacks inside Israel.
During the last Gaza war, in 2014, Hamas fighters used dozens of tunnels to blindside Israel’s superior forces.
The Israeli military said it has destroyed three tunnels in the past two months.
Israel has been constructing a sensor-equipped underground wall along the 60-km (36-mile) Gaza border, aiming to complete the $1.1 billion project by mid-2019.
