Palestinians fired a Qassam rocket at the southern town of Sderot shortly after Barak gave the green light to implement the defense establishment's recommendations to impose limitation on the Strip.
The Hamas-led government in Gaza also expressed its dissatisfaction with the defense minister's decision, which was defined as an implementation of Israel's gradual disengagement from the Gaza Strip.
Taher al-Nunu, a spokesman for the Gaza government, said that this was "a crime against a million and a half Palestinians living in the Strip."
According to al-Nunu, Barak's decision "is part of the collective punishment policy against the Palestinian population."
Although spokespersons for the Palestinian organizations said that "the sanctions will not subdue the Palestinian people," a spokesman for the Democratic Front for the Liberation of Palestine warned that "the decision is a severe escalation which may lead to a humanitarian disaster in the Strip."
According to the spokesman, "The decision contradicts every human rights treaty in the world and may bring about an ecological and health disaster which will turn into a comprehensive humanitarian disaster."
Palestinians in the West Bank also expressed their objection to the Israeli decision.
Dr. Saadi al-Krunz, the Salam Fayyad government's secretary-general, declared that "the Palestinian government opposes the decision, which is basically a collective punishment which we condemn."
According to al-Krunz, "The Israeli decision will bring about a further deterioration in the Strip residents' situation." He demanded that the international community intervene in a bid to cancel the Israeli decision.
Over the past few days, the Palestinians have stressed that the shortage in basic commodities in the Strip is expected to increase in the near future.
Gaza's governor told a Red Cross delegation on Wednesday that while the Strip was in need of 200 trucks carrying food and humanitarian aid in light of the growing unemployment rate, Israel only allowed up to 60 trucks to enter Gaza.
