Israeli warplanes carried out raids on the Nuseirat refugee camp in central Gaza Strip, on Rafah in the south, and on Khan Younis early on Wednesday.
At least three raids were also carried out on the Palestinian city of Beit Lahia.
On Tuesday, Hamas and Islamic Jihad denied launching rockets from the Gaza Strip into the Occupied Palestine, following reports in Israeli media claiming that five rockets had landed in southern occupied territories hours earlier.
According to the Israeli army, at least one of the rockets hit the town of Gan Yavne with no reports of damages or casualties, Press TV reported.
