The IDF statements said a number of terror sites were targeted in the large-scale attack, including an offensive terror tunnel built by the Hamas organization in the Zaytun neighborhood towards Israeli territory; a military compound in the area of Deir ElBalah which belongs to the Hamas, including weapon manufacturing sites.
The IDF "sees with gravity attempts by Hamas to use supposedly spontaneous popular demonstrations to turn the border region into an arena of conflict and to execute terrorist operations", an army statement said.
Israeli jets pounded the Gaza Strip on Saturday after four soldiers were injured in an explosion along the border fence of the Palestinian enclave.
The Hamas is accountable for this incident and its consequences, as well as everything happening in and from the Gaza Strip, above and below ground, said the Israeli army.
Israeli Prime Minister Benjamin Netanyahu, in Germany for the Munich Security Conference, described the border incident as "severe".
Palestinian sources said there were no injuries or deaths from the airstrikes. But he insisted that "from our point of view Hamas is responsible" and said the explosive had been planted during a protest arranged by the group on Friday.
It was one of the most serious incidents on the border of the Hamas-ruled blockaded enclave since the Islamist movement and Israel fought a war in 2014.
The Israeli army responds automatically to any strikes on its territory, generally targeting Hamas facilities.
The exchange is typical of the post 2014 war reality established along the volatile frontier in which Israel carries out limited retaliations to any militant provocations in Gaza.
Israeli aircraft hit Hamas targets in the southern Gaza Strip repeatedly in early February, after it said Palestinians there fired a rocket into the Jewish state.
