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.

Israeli Prime Minister Benjamin Netanyahu on Monday told visiting U.S. mediator Amos Hochstein that a "fundamental change" was needed after nearly a year of cross-border exchanges with Hezbollah in Lebanon.

Displaced residents of the border area would not be able to return home "without a fundamental change in the security situation in the north" and Israel "will do what is necessary to ensure its security," Netanyahu told Hochstein, according to a statement from the Israeli leader's office.

Israeli reports indicate that Defense Minister Yoav Gallant opposes a major military operation against Lebanon at this time, as a senior Israeli army commander is actively pushing for a ground offensive, with Prime Minister Benjamin Netanyahu appearing, at least outwardly, to back the demand for an operation and even threatening once again to fire his defense minister.

The Kan public broadcaster and Channel 13 news both report that Northern Command chief Ori Gordin is pressuring decision-makers to launch a large-scale attack, while Gallant and Israeli army chief Herzi Halevi are far more reserved.

Israel’s top general commanding the restive northern frontier has reportedly begun actively lobbying leaders to okay a ground offensive into southern Lebanon with the goal of securing a buffer zone and halting Hezbollah’s attacks on Israeli settlements in the Galilee, amid disagreements over the matter among politicians and defense brass.

Hezbollah said Sunday that it fired dozens of Katyusha rockets at the Rawya barracks in the Israeli-annexed Golan Heights in response to attacks on Lebanese towns, especially on the town of Sarafand which is distant from the border.

Hezbollah said Saturday that it fired dozens of Katyusha rockets at an Israeli artillery and precision missile base in Yiftah Elifelet northwest of Lake Tiberias, deep in northern Israel.

U.S. mediator Amos Hochstein will soon visit Tel Aviv as well as Lebanon, al-Jadeed television quoted sources as saying.
