Israeli security establishment ordered the full closure of all goods crossings between Israel and Gaza after Palestinian militants in Gaza fired more than 35 Qassam rockets and mortar shells early Wednesday at the western city of Negev.
Israeli security heads are scheduled to meet later Wednesday to discuss whether or not to open the crossings on Thursday.
Local communities of the western Negev have raised the alert level after the bombardment, which caused no injuries or damages.
At least one rocket landed in central Ashkelon, and two others landed near the city. Two women and a 13-year-old girl suffered from shock, the website of local daily Yedioth Ahronoth reported.
Hamas has claimed responsibility for the attacks.
Earlier on Wednesday morning, Israel airstriked central Gaza Strip and killed six Palestinians, including five Islamic Hamas militants and a Palestinian woman.
On Tuesday, three IDF soldiers were injured in the first operation in Gaza since the Egypt-brokered ceasefire took effect in June 19 and six Palestinian gunmen were killed.
The military action was aiming at destroying a tunnel which Gaza militants had dug under the border to try to abduct soldiers, according to an IDF spokeswoman.
Israeli officials said they remained committed to the cease-fire with Hamas, stressing that the operation was an isolated one.
The number of rockets that fired into Israeli territory declined sharply since a truce was declared between Israel and Hamas in June.No one was injured in any of the attacks, but slight damages were reported.
In response to the violations of the ceasefire terms, Israeli Defense Ministry ordered to close down the border crossings to Gaza on several occasions.
