Palestinian terrorists fired a rocket into Israel in the third such violation of the Gaza Strip truce.
A rocket struck the southern kibbutz of Gevim on Thursday afternoon, causing no casualties.
Foreign Minister Tzipi Livni said later that Israel should launch a military response to the violation of the week-old, Egyptian-brokered Gaza cease-fire.
Al-Aksa Brigades, an armed wing of Palestinian Authority President Mahmoud Abbas’ Fatah faction, claimed responsibility for the attack. The group called it retaliation for Israeli military raids in the West Bank, which are not included in the cease-fire.
Israeli defense officials, who suspended imports into Gaza after two separate shelling attacks Tuesday, had said they would reopen the Gaza-Israel border crossings Friday if there were no more shellings.
Tuesday’s attack, claimed by Islamic Jihad terrorists, wounded two people in Sderot. Israel did not retaliate militarily and Hamas, which controls Gaza, said it was trying to keep other factions from firing further rockets and mortars.
Israel says it holds Hamas responsible for any attack from Gaza.
