Residents of the Khan Yunis area in Gaza reported hearing two explosions, the Associated Press news agency said.
The attack was carried out on a Hamas infrastructure site in response to a rocket, fired from Gaza several hours earlier, a statement from the Israeli defense reads.

No casualties were reported as a result of the attack.
Israel and Palestine agreed on an open-ended ceasefire, brokered by the Egyptian government, on August 26.
The truce followed an escalation in the Israeli-Palestinian conflict, which happened in June after Israel laid the blame for the death of three Israeli schoolboys on Hamas, a radical Palestinian Islamic organization and the de facto authority in Gaza. In response, Israel launched its operation "Protective Edge." Over 50 days of hostilities, 2,100 Palestinians and 73 Israelis lost their lives.
Palestinians want to create an independent state on the territories of the West Bank, including East Jerusalem, partially occupied by Israel, and the Hamas-controlled Gaza Strip, and want Israel to withdraw from the Palestinian territories it took after the Six-Day War in 1967.
