Four Qassam rockets were fired towards the town of Sderot and the western Negev from Gaza Monday morning.
The first rocket landed in an open field near the border fence, and the other three apparently fell outside Sderot. No injuries or damage were reported in the incident.
The police combed the area in search of the rockets' landing sites.
Defense Minister Amir Peretz stated recently that RAFAEL will develop and manufacture a short-range rocket interception system, which will be used against Qassams and Katyushas.
The anti-rocket system will be put to use in the Sderot and near-Gaza areas first, and only later in other areas currently under threat, including Ashkelon.
The Islamic Jihad has recently declared that the continued rocket attacks against Israel are aimed at "reminding the Palestinians that they have a common enemy," and that they should therefore out a stop to the internal clashes between them.
