Israel has no intention of deliberately harming the residents of Tehran, Israeli Defence Minister Israel Katz said, walking back earlier comments he had made on Monday.

Dozens of others were injured overnight across Israel, the authorities said. Israel was striking military sites in Iran and the four-day-old conflict showed no sign of slowing.

Israel and Iran exchange missile attacks for a third day; nuclear sites hit, death tolls rise, airspace shut, U.S. warns Tehran against retaliation.

In a small, tight-knit town near Haifa in northern Israel, residents here never thought they would experience such horror.

The Israeli military said that its air force has struck a number of command centers of Iran’s Islamic Revolutionary Guard Corps. It said that the command centers, which were in Tehran, were used to direct proxy groups to launch attacks against Israel.

Israel and Iran kept up their attacks, killing and wounding civilians and raising concern among world leaders meeting in Canada this week that the biggest battle between the two old enemies could lead to a broader regional conflict.

Israel has targeted Iranian energy infrastructure, including the world’s largest gas field, South Pars, which Iran shares with Qatar. CNN’s Becky Anderson speaks with analyst Firas Maksad about how this escalation poses a significant threat to global energy security.

Jonathan Conricus, a former IDF spokesperson, says Iran is "the weakest that I've ever seen it" after Israel's launch of Operation Rising Lion.
