The Israeli air force struck a Hamas target in the north of the Gaza Strip on Sunday, in response to “explosive devices” targeting the Jewish state, according to officials.

“Today, explosive devices were hurled from the Gaza Strip at Israel’s border fence,” the Israeli army said on Twitter.

The army said one of its aircraft targeted a Hamas military post in response.

The reported strike came after a Hamas security source said Sunday that Israeli aircraft had struck its observation points elsewhere in the Gaza Strip late Saturday.

Those strikes – east of Al-Bureij in the central Gaza Strip and east of Rafah in the south of the Hamas-run Palestinian enclave – did not wound anyone, the Hamas security source said.

The strikes occurred after a “cluster of balloons carrying an explosive device was launched from the Gaza Strip towards Israeli territory,” the Israeli army said in a statement.

“No injuries or damage were reported.”
