Israeli warplanes launched two new raids early Wednesday on tunnels linking the Gaza Strip to Egypt without causing casualties, witnesses said.
An Israeli army spokesman confirmed the bombings, saying three tunnels had been attacked and "secondary explosions took place in one of them, indicating the presence of explosives."
On Tuesday, the airforce had carried out some seven raids wounding four people.
Palestinian witnesses said aircraft carried out at least seven strikes along Gaza's southern border.
Four people were wounded in the raids, Palestinian medics said.
