Israel-Gaza updates: Netanyahu weighs plan to force civilians out of north Gaza

The Israeli strike on Beirut on the heels of pager and walkie-talkie explosions this week are designed to emphasize to Hezbollah and Iran the depth of the security breach Israel has achieved, two intelligence sources told ABC News.

The sentiment is if the Israelis can plant exploding pagers and radios, they could have already placed sources and devices that reveal key info and personnel in places thought to be protected, sources said.

The Israelis could well be trying to soften the ground for an assault, but the sources believe the consequence of this week’s events could actually be a realization by Iran and Hezbollah that a return to the uneasy status quo on the northern border might be the right move right now.

Prior to the pager explosions, Israeli intelligence had been running out of actionable information about locations and patterns of life among top Hezbollah officials. Learning where the pagers and radios were and who had them created an invaluable trove of intel.

A key Hezbollah commander and members of his chain of command were killed in an Israeli strike in Beirut on Friday, according to the Israel Defense Forces, as tensions continue to rise along the Israel-Lebanon border.

At least nine people, including a key Hezbollah member, were killed in an Israeli strike on southern Beirut Friday.

Ibrahim Aqil, a senior member of Hezbollah and the target of the strike in southern Beirut, was killed, according to the Israeli army. Top operatives and the chain of command of the Raduan unit were also killed in the strike, according to the Israel Defense Forces.

Aqil and the commanders who were killed were allegedly planning to occupy Galilee, in what Israel claimed would have been similar to Hamas' Oct. 7 attack, IDF spokesman Daniel Hagari said in a statement.

Germany is being selective with what arms it is sending to Israel in light of rising tensions with Hezbollah and Hamas.

“There is no ban on licenses for arms exports to Israel and there will be no ban. The Federal Government decides on the granting of licenses for arms exports on a case-by-case basis and in the light of the respective situation after careful examination, taking into account foreign and security policy considerations in accordance with legal and political requirements,” the German Federal Ministry for Economic Affairs and Climate Protection said in a statement.

“In doing so, the Federal Government takes into account compliance with international humanitarian law. In this case-by-case assessment, the current situation is always taken into account, including the attacks on Israel by Hamas and Hezbollah as well as the course of the operation in Gaza,” the ministry said.
