IAF aircraft struck terror targets in Gaza twice on Saturday night , the IDF Spokesman's Unit announced early Sunday. The IAF recorded direct hits on targets including a weapons manufacturing site.

At least four Palestinians were injured in the strikes, according to Palestinian Ma'an news agency. One person was wounded in the first IAF strike in the Zeitoun area, and three others were wounded in the following attack that hit a "house in the Tofah area east of Gaza City," according to the report.

The IAF strikes came after Palestinians in Gaza took advantage of stormy weather to fire rockets at large southern cities over the weekend.

On Saturday, a Grad-type rocket was launched in the direction of the Negev’s largest city, Beersheba, triggering air raid sirens. Two other rockets exploded in fields in the farming districts of the western Negev.

No one was injured and there was no damage.

The upsurge in attacks began on Friday evening, when Palestinians fired projectiles into the South, setting off sirens in Ashkelon.

Two rockets exploded in the Eshkol farming region of, hitting open fields, according to police.

Last week, Ashkelon Regional Council head Yair Farjun told The Jerusalem Post that Israel could not “tolerate” endless rocket attacks on civilians.

“It must be made clear to them [the terrorists] that there is a price to this,” he said.

At least 30 rockets have been fired from Gaza into Israel since the beginning of 2012, according to the IDF.

Also on Friday, Palestinians fired a rocket-propelled grenade at soldiers stationed near the Gaza border fence, the IDF Spokesman’s Office said.

No injuries were reported in the attack, but the fence was damaged.

The terrorists set off a bomb on the Gaza side of the border upon the arrival of IDF reinforcements. No injuries were reported in the second explosion.
