Iranian missiles struck Israel’s Tel Aviv and the port city of Haifa before dawn on Monday, killing at least eight people and destroying homes, prompting Israel’s defence minister to warn that Tehran residents would “pay the price and soon”.

The dangers of further escalation loomed over a meeting of the Group of Seven leaders in Canada, with US President Donald Trump expressing hope on Sunday that a deal could be done, but no sign of the fighting abating on a fourth day of war.

The latest fatalities in Israel, reported by Israel’s national emergency services, raised its death toll to 23 since Friday. Israeli attacks in Iran have killed at least 224 people since Friday, Iran’s health ministry has said.

At least 100 more were wounded in Israel in the overnight blitz, part of a wave of attacks by Tehran in retaliation for Israel’s strikes targeting the nuclear and ballistic missile programmes of sworn enemy Iran.

Search and rescue operations were underway in Haifa, where around 30 people were wounded, emergency authorities said, as dozens of first responders rushed to the strike zones. Fires were seen burning at a power plant near the port, the media reported.

Video footage showed several missiles over Tel Aviv and explosions could be heard there and over Jerusalem. Several residential buildings in a densely populated neighbourhood of Tel Aviv were destroyed in a strike that blew out the windows of hotels and other nearby homes just a few hundred meters from the U.S. Embassy branch in the city. The US ambassador said the building sustained minor damage, but there were no injuries to personnel.

Guydo Tetelbaun was in his apartment in Tel Aviv when the alerts came in shortly after 4am.

“As usual, we went into the (shelter) that’s right across the street there. And within minutes, the door of the (shelter) blew in,” the 31-year-old chef said.

“A couple of people came in bloody, all cut up. And then when we came to the apartment, after it quietened down, we saw there wasn’t much of it… Walls are caved in, no more glass,” he added.

“It’s terrifying because it’s so unknown. This could be the beginning of a long time like this, or it could get worse, or hopefully better, but it’s the unknown that’s the scariest.”

The predawn missiles also struck near Shuk HaCarmel, a popular market in Tel Aviv that typically draws large crowds of residents and tourists buying fresh fruit and vegetables, and to popular bars and restaurants. A residential street in nearby Petah Tikva and a school in the ultra-Orthodox Jewish city of Bnei Brak were also hit.

‘NEW METHOD’

Iran’s Revolutionary Guards said the latest attack employed a new method that caused Israel’s multi-layered defence systems to target each other and allowed Tehran to successfully hit many targets, without providing further details.

The Israeli Defence Force did not immediately respond to a request for comment on the strikes. There were no reports in Israel of interceptor missiles hitting each other. Israeli officials have repeatedly said its defence systems are not 100% and have warned of tough days ahead.

Israeli Defence Minister Israel Katz said in a statement: “The arrogant dictator of Tehran has become a cowardly murderer who targets the civilian home front in Israel to deter the IDF from continuing the attack that is collapsing his capabilities.”

“The residents of Tehran will pay the price, and soon.”

When asked about the Reuters report, Israeli leader Benjamin Netanyahu told Fox News on Sunday: “There’s so many false reports of conversations that never happened, and I’m not going to get into that.”

“We do what we need to do,” he told Fox’s “Special Report With Bret Baier.”

Israel began the assault with a surprise attack on Friday that wiped out the top echelon of Iran’s military command and damaged its nuclear sites, and says the campaign will escalate in the coming days.

Iran has vowed to “open the gates of hell” in retaliation.

Trump has lauded Israel’s offensive while denying Iranian allegations that the U.S. has taken part and warning Tehran not to widen its retaliation to include US targets.

Two US officials said on Friday that the US military had helped shoot down Iranian missiles that were headed toward Israel.

Trump has repeatedly said Iran could end the war by agreeing to tough restrictions on its nuclear programme, which Iran says is for peaceful purposes but which Western countries and the IAEA nuclear watchdog say could be used to make an atomic bomb.

Iran’s President Masoud Pezeshkian told parliament on Monday Tehran has no intention of building nuclear weapons but it would continue to pursue its right to nuclear energy and research.
