Israel has widened its assault on Iran, striking the Islamic Republic’s energy sector and Defense Ministry headquarters while Iran answered with missiles that killed civilians in Israel and damaged homes around Tel Aviv.

AP says the latest exchanges came after Israel’s surprise offensive began two days earlier against Iran’s nuclear program. In the latest round, Israeli attacks hit energy infrastructure and a defense-related target in Tehran, while Iranian missiles killed an 80-year-old woman, a 69-year-old woman and a 10-year-old boy in central Israel. In the Galilee region, four people were killed in an apartment building, according to Israeli emergency officials.

The scale of the fighting has moved the crisis beyond symbolic retaliation. AP reports that Israel’s strikes have already killed top generals, nine senior scientists and experts tied to Iran’s nuclear program, while Iran’s U.N. ambassador said 78 people had been killed and more than 320 wounded. Those figures are part of competing wartime narratives, but they underline how quickly the exchange has become lethal on both sides.

The conflict has also disrupted diplomacy. Planned U.S.-Iran negotiations over Tehran’s nuclear program were cancelled, and world leaders called for de-escalation. China’s foreign minister warned that attacks on nuclear sites set a dangerous precedent. AP also says the International Atomic Energy Agency and U.S. intelligence agencies had previously said Iran was not actively pursuing a nuclear weapon before Israel launched its campaign, even as Tehran’s enrichment reached near weapons-grade levels.

That background matters because it explains why each new strike now carries a larger strategic risk. Israel’s leadership says it is trying to destroy Iran’s nuclear program. Iran says it is defending itself and, through its Revolutionary Guard, claims its missiles targeted fuel production facilities for Israeli fighter jets. The civilian death toll in Israel shows the conflict is no longer theoretical. It is already exacting a cost that could make the next decisions harder, not easier.

If the fighting keeps expanding, the risks will no longer be limited to the nuclear file. Energy infrastructure, command centers and civilian neighborhoods all become part of the same escalation ladder, which makes miscalculation more dangerous.

AP’s reporting suggests both governments are still trying to justify their actions as defensive or necessary. The difficulty now is that each additional strike makes the political room for compromise smaller and the military costs larger.

The bigger danger is that neither side appears to have a quick off-ramp. With talks cancelled and strikes still hitting symbolic and strategic targets, the conflict now has its own momentum, and each side is likely to read restraint as weakness.

The result is a conflict with fewer and fewer buffers. Military targets, energy infrastructure and civilian neighborhoods are all now part of the same cycle, which raises the odds of a misstep.

That is why the new phase is so dangerous. Once the fighting reaches that many layers at once, the chance of a contained exchange falls quickly.
