Israeli media reported on Wednesday that concerned circles have estimates that the Islamic Resistance Movement (Hamas) will respond to the assassination of Saleh Al-Arouri, deputy head of its political bureau, on the Lebanese side, with moderate participation from Hezbollah likely.

The Israeli Broadcasting Authority said that estimates indicate that since those who were killed yesterday, Tuesday, in Beirut, are practically responsible on a daily basis for Hamas’ shooting from Lebanon, this means that the movement will prepare a response to the assassination, and this may take some time.

It added, "In Israel they estimate that there will be a response from Hamas from Lebanon in all forms and possibilities in response to yesterday's assassination. At least they will try."

Regarding the Hezbollah issue, the source continued, “The assessment in Israel at the moment is that despite the fact that the attack on Al-Arouri was in the heart of the suburb, they will most likely look for some kind of middle response that will show shooting, but will not lead to war or Large-scale event.

The Israeli Broadcasting Corporation warned that police officers in various police directorates were instructed to increase vigilance in anticipation of attacks after Al-Arouri's assassination.

It indicated that special preparations are being made throughout Israel.

On Tuesday, the Israeli Walla news website quoted an unnamed Israeli official as saying that Israel is preparing for a major retaliatory response by Hezbollah to the assassination of Al-Arouri, including launching long-range missiles at targets in Israel.

On Tuesday evening, the Lebanese News Agency said, “An air strike with three missiles from an Israeli drone targeted a Hamas headquarters in the southern suburb of Beirut, resulting in 7 killed and the injury of 11 others,” while Hamas mourned in a statement Al-Arouri and the leaders of the Al-Qassam Brigades, Samir Effendi and Azzam Aqra’. And 4 other members of the movement.

The Hebrew newspaper Yedioth Ahronoth said that shortly after the assassination in Beirut, Hezbollah fired an anti-tank missile at the Moshav Margaliot area on the Lebanese border.

Last August 28, Hezbollah Secretary-General Hassan Nasrallah warned that “any assassination on Lebanese soil that targets a Lebanese, Palestinian, Syrian, Iranian, or others will have a strong reaction, and we will not allow the Lebanese arena to be opened to assassinations.”

The assassination in Beirut comes at a time when Lebanon's southern border has witnessed daily confrontations and bombing between Hezbollah and the Israeli occupation army since last October 8, resulting in dozens of deaths and injuries on both sides of the border.
