Israeli Prime Minister Benjamin Netanyahu hinted at potential revenge as he affirmed his nation's right to self-defense following Iran's unprecedented attack, asserting Israel's sole authority in determining its response.

Iran launched over 300 drones and missiles at Israel over the weekend, resulting in minimal damage due to the interception of most projectiles.

The Israeli military has vowed retaliation, sparking diplomatic efforts to de-escalate tensions in the region.

Israel's allies in Washington and Brussels have pledged increased sanctions against Iran. British Foreign Secretary David Cameron and his German counterpart Annalena Baerbock became the first Western envoys to visit Israel since the attack.

Netanyahu informed the visiting ministers that Israel "will reserve the right to protect itself," according to his office.

The pair offered "all kinds of suggestions and advice" during a meeting, Netanyahu said. "However, I would also like to clarify: We will make our decisions ourselves."

For his part, Cameron said, "We're very anxious to avoid escalation and to say to our friends in Israel: It's a time to think with the head as well as the heart."

Baerbock emphasized that "the region must not slide into a situation whose outcome is completely unpredictable."

Tehran has vowed to hit back if its arch-foe Israel responds to the Saturday attack, which itself was launched after a deadly strike on Iran's Damascus Consulate building earlier this month that was widely blamed on Israel.

Citing three unnamed Israeli sources, ABC News reported on Thursday that "Israel prepared for and then aborted retaliatory strikes against Iran on at least two nights this past week."

Among the range of possible reactions considered by the Israeli War Cabinet were options to attack Iranian proxies elsewhere in the region or to conduct a cyberattack, the sources told ABC.

Meanwhile, the war in Gaza that has sent regional tensions soaring continued unabated, with efforts at a truce appearing to flounder, as key mediator Qatar said it was re-evaluating its role in the stalling negotiations.

Iran sanctions pushed

Iranian President Ebrahim Raisi warned after the attack of "a fierce and severe response" to any retaliation and on Wednesday, his country celebrated its annual Army Day with a parade featuring various attack drones and long-range missiles.

Also on Wednesday, Tehran-backed Hezbollah wounded 14 soldiers, six seriously, in a strike on northern Israel, the Israeli army said.

This was the third day in a row the Lebanese group had wounded people in Israel amid near-daily cross-border fire since the start of the Israeli-Palestinian war.

Later, Israel hit targets in eastern Lebanon, far from the border, a Hezbollah source told Agence France-Presse (AFP).

Israel's top ally, the U.S., has made clear it won't join any attack on Iran, vowing instead to level more sanctions against the country's missile and drone program, its Islamic Revolutionary Guard Corps and the Iranian Defense Ministry.

Nevertheless, on Wednesday, U.S. Republicans unveiled a bill that would provide $26 billion of military aid to Israel, which appeared to have White House backing.

E.U. foreign policy chief Josep Borrell said Brussels was also working to expand sanctions against Iran, including its supply of drones and other weapons to Russia and to proxy groups around the Middle East.

French President Emmanuel Macron said the E.U. and its allies had a "duty ... to expand these sanctions," while Baerbock said Berlin backed further sanctions.

Cameron also urged the G-7 to adopt new "coordinated sanctions against Iran" ahead of a meeting with counterparts from the Western-led grouping in Italy.

Deadly strikes in Gaza

The Israel-Iran tensions have threatened to overshadow the Gaza war, even as deadly bombardment and combat raged in the besieged territory.

Talks toward a truce and hostage release deal have stalled, said Qatari Prime Minister Sheikh Mohammed bin Abdulrahman Al Thani, despite months of effort also involving U.S. and Egyptian officials.

He later said that his country was undertaking "a complete re-evaluation of its role because there has been damage to Qatar," which does not have diplomatic relations with Israel.

The Israeli military said Wednesday that its aircraft had "struck over 40 terror targets throughout the Gaza Strip" over the past day.

When one strike hit the southernmost city of Rafah, where 1.5 million Palestinians are sheltering, Jamalat Ramidan said she "woke up to the sounds of girls shouting 'mama, mama, mama.'"

As she fled the carnage alongside the children, they stumbled over "body parts and corpses scattered all over the place," Ramidan told AFP.

The recent conflict was triggered by an unprecedented incursion on Israel by Hamas on Oct. 7 that resulted in the deaths of around 1,200 people.

Hamas also took about 250 hostages, of whom Israel estimates 129 remain in Gaza.

Israel's devastating retaliatory offensive has killed at least 33,899 people in Gaza, mostly women and children, according to the Health Ministry in the Hamas-run territory.

Aid sent by sea

Israel has faced growing global opposition to the relentless fighting in Gaza, which the United Nations and aid agencies have warned has pushed the north of the territory to the brink of famine.

But Netanyahu rejected any claims about famine on Wednesday, saying Israel is doing "above and beyond" what is needed "on the humanitarian issue," his office said.

The Israeli army said that eight trucks of food aid from the World Food Programme (WFP) that arrived via Ashdod port in Israel had entered Gaza through an Israeli land crossing.

It is the first time U.N. aid has traveled through the seaport since Israel said it would open it earlier this month following international pressure.

Meanwhile, the U.N. Security Council was preparing to vote Thursday on an Algeria-drafted resolution for full U.N. membership for a Palestinian state, diplomatic sources said.

However, the veto-wielding U.S. has repeatedly expressed opposition to the move.
