The Israeli Air Force struck 34 targets in the Gaza Strip early Tuesday, carrying out “precision strikes” against Hamas and Islamic Jihad structures, the IDF said in a statement early Tuesday.

According to reports, sites in Khan Younes, Rafah and Beit Lahia were hit.

“Following over 18 rockets which were fired at Israel since Sunday evening, IAF aircraft carried out a precision strike against 34 targets in the Gaza Strip,” the IDF said.

Four people were injured, according to Israel Radio citing Palestinian sources.

“The IDF will continue to act in order to restore the peaceful living to the civilians of the state of Israel. The Hamas terror organization and its extensions are solely responsible for any terror activities emanating from the Gaza Strip,” IDF Spokesman Lt. Col. Peter Lerner said.

A rocket fired from the Gaza Strip early Tuesday landed in the Eshkol Regional Council, causing damage to several cars and a fire close to a packaging plant, which was quickly put out by emergency services.

Another rocket landed in the Sdot Negev region, causing no damage or injuries.

The air strikes and rocket attacks came hours after the bodies of kidnapped Israeli teenagers — Eyal Yifrach, 19, Gil-ad Shaar, 16 and Naftali Fraenkel, 16 — were found partially buried in a field near the West Bank village of Halhul, north of Hebron.

The teenagers were kidnapped on the night of June 12 at a hitchhiking post outside the settlement of Alon Shvut in the Etzion Bloc south of Jerusalem.

The bodies were found at about 5:30 p.m. Monday, bound and partially buried, in an open field in a hard-to-access area. The site is less than 20 kilometers (12 miles) from where the teens had been abducted.

Israel is on the hunt for two Hamas men it says were behind the kidnappings, Marwan Kawasme and Amer Aby Aysha.

Since the start of Operation Brother’s Keeper to find them, 18 days of searches had seen the arrests of over 400 Palestinians, a majority of them members of Hamas.

On Monday, Hamas operatives launched a large volley of rockets which slammed into Israel, the first time in years the Islamist group has directly challenged the Jewish state, according to Israeli defense officials.

At least 16 rockets were fired at Israel Monday morning, most of them hitting open areas in the Eshkol region, the army said.

The security sources, who spoke on condition of anonymity, assessed that Hamas had probably launched the barrage in revenge for an Israeli airstrike several hours earlier which killed one person and injured three more.

A member of Hamas’s militant wing was killed in the attack, Gaza health official Ashraf al-Kidra said.

While Israel has maintained it holds Hamas responsible for all rocket attacks, officials have said that smaller groups, such as Islamic Jihad, are usually behind the rocket attacks, while Hamas squads generally attempt to thwart the rocket fire.

Hamas hasn’t fired rockets into Israel since Operation Pillar of Defense ended in November 2012, and has yet to take responsibility for this latest barrage.

The group fired hundred of rockets at Israel over eight days during Operation Pillar of Defense in 2012, as Israel carried out punishing strikes on the Palestinian enclave.

Officials said Monday’s rocket attacks, which appeared to deliberately target Israeli communities close to the border with the Gaza Strip, may have been intended to warn Israel against targeting Hamas operatives.

The army said in a statement that the Sunday night air raid was targeting terrorists “in the southern Gaza Strip, during​ their final preparations to launch rockets at civilian communities of southern Israel.”

“Hamas is responsible for the outrageous attacks originating from Gaza, and will be pursued as such,” IDF spokesman Lt. Col. Peter Lerner said.

The air force attack on Khan Younis Sunday night came minutes after Palestinians in the coastal enclave fired a volley of rockets at southwestern Israel. The Iron Dome defense system shot down two of the projectiles — Grad rockets — over Netivot. There were no reports of injury or damage in the rocket attack.

Early Sunday morning, air force planes struck 12 sites in Gaza in response to rockets fired over the weekend. Two rockets hit the town of Sderot, close to the border with Gaza, late Saturday, causing a massive fire that destroyed a paint factory.
