Palestinian terrorists ceased rocket attacks from Gaza into Israel and relative calm prevailed Saturday afternoon after a night-long exchange of fire that prompted Israeli threats against Iranian forces in Syria.

The Islamic Jihad group, a terror faction operating in the Hamas-ruled Gaza but that has close ties to Iran and Syria, said they agreed to Egyptian mediation efforts and halted the rocket fire, the heaviest to emanate from Gaza in months.

“The Egyptian efforts led to understandings to restore calm to Gaza Strip. We appreciate the Egyptian endeavor and hope for all kinds of (Israeli) aggression to stop,” said Khaled al-Batsh, an Islamic Jihad official.

Hamas, the larger terror group that controls Gaza, accused Israel of resorting to military escalation “to evade obligations” of a comprehensive cease-fire that Hamas has long sought. Hamas wants the deal to end a crippling Israeli-Egyptian blockade on Gaza.

There has been no immediate comment from Israel on truce. It has said its fighter jets struck dozens of targets across Gaza and accused Iranian forces in Damascus of orchestrating the barrages.

The threats toward Iranian forces in Syria added a new dimension to what was already the heaviest fighting between Israel and Gaza militants in several weeks. Opening a new front in Syria could put Israel in open confrontation with heavily armed Iranian and Hezbollah forces, along with recently deployed Russian anti-aircraft systems.

Lt. Col. Jonathan Conricus, an Israeli military spokesman, said that 34 rockets had been fired at Israel throughout the night. Israel’s Iron Dome rocket-defense system intercepted 13 rockets, two landed in Gaza and the remainder fell in open spaces in southern Israel, he said. In response, Israel hit over 80 targets in Gaza.

Conricus said Islamic Jihad had fired the rockets under instructions from Iran’s Al Quds Force based in Syria and said that Israel was considering taking action against the Iranians in response.

“We have seen and established a clear link between Gaza and Damascus,” he said. “We know that the orders, incentives were given from Damascus with the clear involvement of the Iranian Revolutionary Guard Quds Force.”

“From our perspective, part of the address by which we will deal with this fire is also in Damascus and the Quds Force,” he added. “Our response is not limited geographically.”

Iran has sent its forces, along with those of Hezbollah and other Shiite militias, to Syria to back President Bashar Assad in the civil war there. As the war winds down, Israel has repeatedly warned that it will not allow its archenemy Iran to establish a permanent military presence in postwar Syria.

Throughout the seven-year war, Israel has already carried out scores of airstrikes in Syria, mostly against suspected Iranian weapons shipments to Hezbollah but also against the Iranians themselves.

But Israel’s mission could become much more complicated following Russia’s decision to transfer sophisticated S-300 anti-aircraft missiles to Syria.

Russia deployed the missiles after a Russian warplane was shot down over Syrian skies last month. Russia has blamed Israel for the mishap, saying that Syria accidentally shot down the plane while reacting to an Israeli air raid.

Israel and Russia have maintained a hotline to prevent their air forces from coming into contact with one another over Syrian skies. Israeli media have reported that Russia has become less cooperative since the downing of the plane.

The fighting in Gaza followed a bloody day of border protests Friday in which Israeli forces shot and killed four Palestinians protesting along the perimeter fence dividing Hamas-ruled Gaza and Israel. A fifth protester succumbed to his wound Saturday, the Health Ministry said.

Egyptian mediators have been trying to prevent a full-blown conflict between Hamas and Israel for months.

Conricus said that Israel had struck over 80 sites across Gaza, including training camps, weapons storage facilities and a Hamas security headquarters building. COGAT, the Israeli defense body that handles Palestinian civilian issues, said one of the rockets hit an ambulance crossing used to transfer Gazans out of the strip in emergency humanitarian cases.

“To what low have the terrorist organizations in the Gaza Strip reached?” wrote COGAT commander, Maj. Gen. Kamil Abu Rukun, on his Arabic Facebook page.

In Gaza, most of the airstrikes hit open spaces used by militants for training and possibly weapons storage.

But in northern Gaza, the Health Ministry said that the main hospital in the area was damaged after a nearby Hamas training camp was hit. Footage showed cables and wires dropping from collapsed ceilings in the wards.

In Gaza City, an airstrike hit an abandoned, unfinished building, flattening the three-story structure. That building appeared to be the one identified by Israel as a security headquarters.

Although Islamic Jihad often acts independently of Hamas, Israel holds Hamas, which has ruled Gaza since 2007, responsible for all fire emanating from the territory.

Conricus said there had been no signs of Hamas trying to rein in Islamic Jihad. He also criticized Hamas for escalating the border protests after Israel had tried to defuse tensions by allowing special fuel shipments into Gaza to improve the supply of electricity. The territory suffers from chronic power outages.

There were no reports of casualties on either side.

Israel and Hamas have fought three wars over the past decade, and Israel and Egypt have maintained a stifling blockade on the territory to weaken Hamas. The Hamas-led weekly protests along the Israeli border have been aimed in large part at breaking the blockade, which has devastated the Gaza economy.

Hamas, an Islamic militant group sworn to Israel’s destruction, had previously scaled down the protests as Egypt stepped up its efforts to secure calm.

Israel accuses Hamas of using the large protests as cover to stage border infiltrations and attacks. It says it is defending its border and accuses Hamas of exploiting young protesters and encouraging them to risk their lives in order to increase pressure to ease the blockade.

Israel has come under heavy international criticism for what many see as excessive use of force and the large number of unarmed people who have been shot.

On Wednesday, Egyptian intelligence officials met representatives of Palestinian factions in Gaza, the latest in a round of shuttle diplomacy between the sides.

Egypt wants to restore calm in order to pursue the broader goal of Palestinian reconciliation between Hamas and the West Bank-based administration of President Mahmoud Abbas. The internationally recognized Abbas lost control of Gaza in 2007.

Hamas has demanded a full lifting of the blockade, which has made it increasingly difficult for Hamas to govern. Widespread desperation among Gaza’s 2 million residents has fueled the participation in the Hamas-orchestrated protests.

Since the marches began six months ago, at least 160 Palestinians present or taking part in the protests have been killed. A Gaza militant fatally shot an Israeli soldier in July.
