European Union's top diplomat Josep Borrell said Tuesday he would seek more information from Beirut, where he just traveled from, as he came before journalists just after news broke from Lebanon of several hundred people being wounded by pagers exploding, including members of Hezbollah.

Suspicion immediately fell on Israel, which earlier Tuesday stressed that halting Hezbollah's attacks on Israel's north to allow residents to return to their homes was now an official war goal.

Officials in Israel's defense establishment are now strenuously contradicting Israeli Prime Minister Benjamin Netanyahu's insistence that Israel maintain control of the narrow strip of land along the Gaza-Egypt border known as the Philadelphi Corridor, and warning that Netanyahu's reluctance to sign a cease-fire deal with Hamas is pushing Israel into a “potentially disastrous war with Hezbollah in Lebanon,” according to Israeli military and senior defense officials who spoke with ABC News.

The Israeli army said Tuesday that Israel’s internal security agency, the Shin Bet, has foiled an imminent “Hezbollah plot” to target a former security official with an explosive device.

Commissioner-General of the U.N. agency for Palestinian refugees, Philippe Lazzarini met Tuesday with Parliament Speaker Nabih Berri and caretaker Foreign Minister Abdallah Bou Habib, in Beirut.

Lazzarini said he discussed with Berri the latest developments in the region including the war in Gaza, the "dramatic" situation in the West Bank, and the clashes in Lebanon.

The upcoming winter factor is what has pushed Israel’s political and military leaders to mull an imminent attack on Hezbollah in Lebanon, the Jerusalem Post has reported.

A U.S. official has told U.S. news portal Axios that "it would be crazy" of Israeli Prime Minister Benjamin Netanyahu to fire an experienced minister of defense like Yoav Gallant amid a war in Gaza and as Israel might be heading towards a possible all out war in Lebanon.

Lebanon has filed a complaint to the United Nations Security Council over an Israeli strike that targeted a civil defense vehicle in the town of Froun in the Nabatieh district earlier this month, the Ministry of Foreign Affairs said Tuesday.

The strike on Froun killed four civil defense members who were on a firefighting mission after Israeli strikes sparked fires in the area.

Speaker Nabih Berri has said that Lebanon has become used to the Israeli threats although they have increased in recent days.

Hezbollah can deter Israel and protect Lebanon, in case Israel decides to expand the war, a member of Hezbollah’s parliamentary bloc said, as Israel said it is considering a wider military operation to allow its northern residents to return home.

Hezbollah MP Raed Berro said Monday that the militant group "is ready for confrontation and has a lot in its pocket to deter the enemy and protect Lebanon in case Netanyahu thinks of expanding the war."

Three people were killed Tuesday and two others were wounded in an Israeli airstrike on the southern border town of Blida, the Health Ministry said.

An Israeli drone also raided the al-Litani river in Zawtar el-Gharbeye.
