A Palestinian terror cell in the Gaza Strip fired a Qassam rocket at Israel in the early hours of Wednesday morning.
The rocket exploded in an open area in the Eshkol Regional Council. There were no reports of injury or damage.
The situation in the south has been calm in recent days, after weeks of increasing rocket attacks.
The last attack was on Friday, when a mortar shell was fired from the northern Strip, and landed in an open area in the Hof Ashkelon Regional Council.
Hamas Prime Minister Ismail Haniyeh urged Palestinian organizations operating in the Strip to "intensify their meetings in order to reinforce the national agreement and to work in a joint spirit to protect our people and to protect our interests and to block any possible Israeli aggression against our people."
Haniyeh said that while he does not foresee another war in Gaza, the Islamist group following the "Israeli escalation" closely.
