A rocket was fired from the Gaza Strip Monday evening, the Israeli army said, but failed to cross into Israeli territory.
A rocket alert was sounded in the kibbutz of Kerem Shalom on the border with Gaza.
The army added that the incident is under investigation.
On Saturday, the Israeli military struck several Hamas targets in the Gaza Strip in the early hours after rockets fired from the enclave were intercepted over southern Israel.
The military said that it had hit a Hamas military post, a factory that produces rockets, and underground infrastructure, after rocket sirens had sounded in the southern city of Ashkelon and nearby communities, the first such attack in more than a month.
Sources in the IDF said it was unclear who was reponsible for the launch, but that there was no directive from Hamas to attack Israel.
The strikes came amid reported indirect negotiations between Israel and Hamas on a prisoner exchange deal and on allowing humanitarian aid into the coastal enclave.

Last month, a rocket fired from Gaza hit a building in the southern city of Ashkelon, causing damage but no injuries or casualties. The Israeli military struck several Hamas targets in Gaza in response. Following the confrontation, an Israeli tank in the area fired at a Hamas position without authorization.
