Israeli aircraft bombed Hamas sites in the Gaza Strip, on Saturday, in response to incendiary balloons launched from the Palestinian enclave, said the Israeli Military.
The political group that governs Gaza reported that the attack targetted what the Israeli military said was a rocket launching site and a compound belonging to Hamas.
There were no immediate reports of casualties or damage, the political group added.
Hamas had no immediate comment.
Three sites were targeted by Israel, including Beit Hanoun and Jabalya, media reported.
Palestinians in Gaza have been launching balloons laden with incendiary material across the border, causing fires that have burned fields in Israel since the Israel-Hamas cease-fire ended on May 21.
Balloon launches had mostly ebbed after Israel eased some restrictions on Gaza.
But on Friday, balloons were again launched from Gaza, causing at least four brush fires in areas near the Israel-Gaza frontier.
The Israeli military said its air raids were a “response to continual launches of incendiary balloons from Gaza into Israel throughout the day”.
