Palestinian sources in Gaza reported that three people were killed and six others were missing following an attack carried out by Israeli aircraft overnight Tuesday on arms smuggling tunnels in the southern part of the Hamas-ruled territory, along the border with Egypt.
Those killed in the attack were brothers aged 24, 26 and 30, medical officials in Gaza said.
The Israeli pilots identified direct hits on the tunnels, while Palestinian rescue teams were continuing their search for additional casualties at the scene.
The Air Force launched the attack in response to Monday's shooting incident near the fence separating Israel from Gaza, during which a Palestinian was killed and an IDF soldier was lightly injured.
On Monday evening Palestinians in north Gaza launched two or three mortar shells towards the Ashkelon area following an attack by IDF forces on a group of teens near Beit Lahiya, during which a 15-year-old boy was killed. The army said the teens approached the border fence and did not heed the soldiers' call to stop.
A soldier sustained light injuries after hitting his head while running for cover during the mortar attack. He was evacuated to Barzilai Medical Center in Ashkelon.
