A Qassam rocket fired from Gaza late Sunday evening hit open spaces in Shaar HaNegev Regional Council. No injuries or damage have been reported.
The fire came just hours after Israel allowed ten trucks stocked with goods for trading, held in its port for three years, into the Strip.
On Saturday Hamas's exiled politburo chief, Khaled Mashaal, met with leaders of Palestinian factions at his home in Damascus, Syria. He told reporters after the meeting that war in the region was entirely possible.
"A conflict with the Zionist enemy is possible in any scenario," he said, adding, "We shall realize our right by standing firm in the face of aggression through resistance."
Meanwhile, Hamas' government in Gaza is trying to avoid further escalation. The Islamist group met with local armed factions and called on them to halt the rocket fire on Israel.
However, the Salafi movement, an extremist Islamic movement identified with global jihad and al-Qaeda, did not take part in the meeting. The movement has claimed responsibility for most of the recent rocket attacks on Israel.
Hamas' security forces have been hunting down Salafi cells operating in Gaza.
