Gaza City: Israeli warplanes fired missiles at targets across Gaza, on Monday, damaging a series of tunnels along the territory's border with Egypt.
Palestinian security officials said Israel had carried out four overnight raids, two of them along the frontier, one in central Gaza and one in the north.
Three cross-border tunnels sustained heavy damage in the raids, although no one was hurt, officials from the Hamas-run security forces said.
Warplanes also targeted an empty house in Beit Hanun in northern Gaza, causing serious damage, as well as an open area in Nusseirat, south of Gaza City.
The Israeli military confirmed the attacks along the border and in the north but made no mention of Nusseirat.
"The Israel air force struck a weapons manufacturing site in the northern Gaza Strip and two weapons-smuggling tunnels in the southern Gaza Strip overnight," a statement said.
The attacks came after Gaza-based militants fired four missiles into southern Israel over the weekend.
Figures cited by the military indicate that more than 100 rockets or mortar rounds have been fired in the direction of Israel since the beginning of the year.
Israel has repeatedly targeted the tunnels on the Egyptian border in retaliation for rocket fire from the Hamas-ruled enclave.
