LIVE BLOG: Three dead, seven injured in Israel-Hezbollah clashes

Palestinian political parties and resistance groups have rallied in the Gaza Strip in support of Hezbollah after the killing of two Israeli soldiers on Wednesday by Hezbollah rocket fire.

Numerous Palestinian groups, including Hamas, Islamic Jihad, Fatah, the Popular Front for the Liberation of Palestine (PFLP) and the Democratic Front for the Liberation of Palestine (DFLP) rallied in the Strip, often distributing sweets to followers, according to the Ma'an news agency.

"The resistance front from Lebanon to the Shebaa (Farms), to Quneitra and to Jerusalem and on to Gaza is a unified front, and any group targeted by the occupation will erupt (in response)," Islamic Jihad leader Khalid al-Batsh said at the event.

He added that Hezbollah had cornered Israel between two options through its attack on the soldiers at the border, forcing it to decide whether to remain silent or to respond and enter a full-on war.

"In either case," he added, "Netanyahu is risking his political future."

Israeli radio reported on Wednesday afternoon that the country’s envoy to the UN told the Security Council in a speech that “Israel will not sit with its hands behind its back when faced with attacks from Hezbollah”.

The envoy said Israel would continue to take all necessary steps to defend itself from attacks by the Lebanese militant group, Anadolu Agency reported.

Israeli Prime Minister Benjamin Netanyahu has levelled the blame for the killing of two Israeli soldiers by Hezbollah on the Lebanese and Syrian governments.

He said that the two governments were "equally responsible for ramifications of attacks against us from their territory."

The soldiers killed in the Hezbollah attack today have been named as Capt. Yochai Klengel, 25 of Har Gilo, an Israeli settlement in the West Bank, and Sgt Dor Nini, 20, from Shtulim in South-Central Israel.

A Spanish UN peacekeeper killed by Israeli shelling has been identified as Francisco Javier Soria.

A commander in the United Nationas Interim Force in Lebanon (UNIFIL) has been in touch with Israel who have stated they have no interest in escalating attacks, according to Sky News Arabia.

The Marxist-Leninist Popular Front for the Liberation of Palestine (PFLP) released a statement on Wednesday praising the attack by Hezbollah that killed two Israeli soldiers.

"The Popular Front for the Liberation of Palestine welcomed the heroic operation that Hezbollah carried out against the Israeli enemy's army patrols in southern Lebanon," it read and also called for a "united front" of Palestinian and Arab forces in the region to fight against Israel.

Tzipi Livni, co-chair of the Zionist Camp coalition, has stated that Israel will respond "harshly" to an attack on the Israel-Lebanon border earlier which killed 2 Israeli soldiers.

"At this time it should be clear to all: Whether this [attack] is Iran acting through Hezbollah, or whether it is the Syrians, an attack on soldiers or civilians will be answered harshly and without compromise by the IDF," said Livni, during a tour of the northern border.

"Hezbollah is part of the extreme Islamist axis in the Middle East and it must be dealt with by force, and the IDF and its soldiers know how to do this precisely and responsibly."

The Israeli army has opened an internal investigation into two 'technical errors' that caused the death of the two soldiers at the hands of the Lebanese Hezbollah group, in the Shaba border farms, according to Ynet.

Sources in Israeli Prime Minister Benjamin Netanyahu's bureau have reportedly blamed Iran for the attack on the Israel-Lebanon border, according to the Jerusalem Post.

“Iran is behind this heinous terrorist attack. The same Iran which the world powers are forming an agreement with, that would allow it to maintain its ability to acquire nuclear weapons capacity,” the sources said.

“We must not give such terrorism a nuclear umbrella. We must not let the most dangerous regime in the world to arm itself with the most dangerous weapons in the world,” the sources said.

Lebanese politician Samir Geagea, leader of the christian Lebanese Forces party, has slammed Hezbollah's attack on Israel complaing that the militant group had "no right to involve the Lebanese army and government in a battle with Israel."

The Lebanese Forces party is part of the March 14 Alliance, a group of parties who hold a broadly anti-Hezbollah stance.

Haaretz has reported 2 Israelis confirmed killed and 7 wounded after being hit by an anti-tank missile in the Har Dov area of Israel near the Lebanon border.
