Erez and Kerem Shalom crossings to be closed following rocket attack on Be'er Sheva.

Defense Minister Avigdor Liberman on Wednesday morning ordered the closing of the Erez and Kerem Shalom crossings to Gaza, as well as the reduction of the fishing area in Gaza to only 3 nautical miles.

The Defense Minister's decision was made following the rocket fire into Israeli territory overnight Tuesday.

A rocket fired from the Gaza Strip exploded in near a home in the southern Israeli city of Be'er Sheva.

Magen David Adom paramedics gave medical treatment to a woman about 50 years of age and a 40-year-old man who suffered light injuries while running to a protected area. In addition, a 20-year-old woman who suffered from shock was evacuated to the Soroka Hospital.

The residents of the home were treated for shock, including a 39-year-old woman and her three children aged nine, ten and twelve. Two other residents who live nearby were treated for shock as well.

A total of nine people were treated by Magen David Adom teams.

In addition, the building sustained damage.

Before the explosion, sirens were heard shortly after 3:30 a.m. local time in Be’er Sheva and the surrounding area.

The IDF confirmed that, in addition to the rocket that exploded in Be’er Sheva, a second missile fired at the same time landed in the sea.

Tuesday night’s incident took place hours after Liberman warned that Hamas would be dealt a harsh blow if the escalation in the region continues.

Speaking following a security assessment, Liberman said that Israel is “not prepared to accept the level of violence that we see week after week…We have exhausted all the options, all the possibilities, and now the time has come to make decisions."

He then added, “We must strike Hamas hard, and this is the only way to bring the situation back to normal and lower the violence threshold to 0 or almost 0, or to the level of March 29.”
