Witnesses said the aircraft attacked four security positions belonging to Hamas, the Islamist movement that runs the Gaza Strip, and that the two people hurt were passers-by.
The Israeli military said that earlier a rocket fired from the enclave landed in an open area in southern Israel, causing no casualties. It had no immediate comment on the air strikes.
There was no immediate claim of responsibility for the Palestinian rocket fire. Israel has said that Hamas bears overall responsibility for what happens in the territory.
The group has observed a de-facto cease-fire with Israel since a 2014 war but small armed cells of Jihadist Salafis have continued to occasionally launch rockets at Israel. When those attacks occur, Hamas usually orders its fighters to vacate potential targets for Israeli retaliation. (Reporting by Nidal Al-Mughrabi-Arab News
