The Israeli military issued a statement in the early hours of the 18th saying that it launched a series of air strikes in southern Gaza that day, targeting a "weapons manufacturing base" of the Palestinian Islamic Resistance Movement (Hamas).
There were no casualties in the attack.
Israel said it intercepted a Hamas rocket fired from Gaza on the 17th.
It was the first time in recent months that Hamas had fired rockets into Israel.
In response, a Hamas spokesman said the Israeli airstrikes only hit "open spaces".
Recently, conflicts in the Palestinian-Israeli region have continued, and the situation has become tense again.
Since the 15th, Palestinians and Israeli police have continued to clash near the Al-Aqsa Mosque in the Old City of Jerusalem, causing more than 170 Palestinians to be injured.
