Defense Minister Ehud Barak ordered the Gaza crossings remain closed on Tuesday. Despite the order, Israel will allow some 100 trucks carrying humanitarian aid to cross into the Strip through the Kerem Shalom crossing.
The trucks, carrying basic food and medical supplies donated by the Turkish and Jordanian governments and various international organizations, are due to enter the Hamas-controlled territory through the Kerem Shalom crossing.
Five ambulances donated by Turkey to the Palestinian emergency services will also be allowed to pass.
Barak's decision came despite Monday's massive rocket and mortar barrages, which claimed the lives of three Israelis and injured nine others, one of them seriously.
Some 90 rockets were fired toward Israel since Monday morning, some of them hitting locations 40 kilometers (about 25 miles) deep in Israeli territory.
Following a security assessment at his Tel Aviv office Monday, Barak issued a staunch warning to Hamas, and called on Gaza's residents to refrain from entering "terror zones".
