| With the conflict between Israel and Iran in its fourth day, we checked in with Bloomberg’s Tel Aviv bureau chief Ethan Bronner for a sense of the mood on the streets—and in the safe room at his apartment.

I figured it was a Houthi missile, which had landed almost nightly in recent weeks, upsetting but not alarming: one projectile coming from Yemen against a formidable Israeli air defense system. But a closer glance at the messages jerked me fully awake: Israel had launched a massive surprise attack on Iran, and everyone was instructed to head to a bomb shelter or protected space in anticipation of Iranian retaliation. Schools would be closed; work canceled; the airport shut down. I quickly went to the protected space of my Tel Aviv apartment. And since it doubles as my study, I opened my computer and got to work. Newer buildings in Israel must have a safe area in each apartment rather than a collective shelter in the basement. The room where I’m writing this is secured by 12-inch-thick reinforced concrete walls, an airtight steel door, a blast-resistant shutter on the window and an air filtration system to guard against chemical weapons. We knew Israel was deep into plans for an attack on Iran, but it was widely assumed—including, to their detriment, by the Iranians—that any action wasn’t imminent. A sixth round of talks with the US over Iran’s nuclear program was due on Sunday, and an attack before that seemed unlikely. Moreover, Prime Minister Benjamin Netanyahu’s son was due to be married on Monday. Surely he’d wait until after that. He didn’t (the wedding’s been postponed). Some 200 Israeli planes made their way 1,100 miles to Iran and, supported by drones smuggled in by intelligence agents months before, pulled off a punishing assault. Israel killed more than a dozen Iranian generals and nuclear scientists, took out air defenses and missile launchers, and damaged a uranium enrichment site. It was such a blow that it took time for Tehran to muster a response. We waited in or near safe rooms for hours, then finally at 11 a.m., we got the all clear to go about our business. It was a strange interlude. Restaurants had been ordered closed, though some were offering takeout. Supermarkets quickly filled with people shopping for Sabbath meals—and hoarding essentials, clearing some shelves. I took a walk by the sea and wasn’t alone. The beaches weren’t as full as they might normally be on a summer afternoon. But they weren’t empty. Tel Avivians were happy to breathe freely for a few moments.

As I sat in my study, missiles began to rain down. And so began a cycle of attacks and counterattacks. Israel has hit energy facilities, more nuclear sites, key military figures and missile launchers; Iran has fired off ballistic missiles, most stopped by Israel’s air defense, but some getting through, slicing open high-rise buildings. Hundreds of Iranians and two dozen Israelis have been killed. Most of the missiles arrive at night, making for fitful sleep. This morning, I was awakened at 4 a.m. by another barrage. I heard sirens and then booms that shook the building. It felt uncomfortably close. And it was. After the all clear, I stepped out into the warm summer morning and headed over to the affected area, already crawling with soldiers, police and clearance crews. Walls hung from buildings, glass plates were shattered, cars were smashed, trees down. It was a half-mile from home. And this is only the fourth day.
