The latest attack was the third round of airstrikes in Gaza that started early on Saturday.
"Over the past hour, the Israeli Air Force attacked dozens of sites on the territory of four military installations belonging to the Hamas terrorist organization," the IDF press service said.
Earlier in the day, IDF said over 30 mortar shells have been launched toward Israel from the Gaza Strip overnight during an exchange of fire between the two sides.
Tensions on the Israeli border with Gaza had flared up due the Great March of Return rally, which began on March 30, in order to mark the 70th anniversary of the foundation of Israel and protest the moving of the US embassy to Jerusalem, which Palestinians consider to be their capital.
