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

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 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.

Israel's military spokesman said that the country’s air force has destroyed 120, or about one-third, of Iran’s surface-to-surface missile launchers since the beginning of its confrontation with Iran.

Iran and Israel continued on Sunday their aerial attacks, which began Friday with a series of Israeli strikes on Iran.

A volley of missiles launched by Iran killed eight people and injured nearly 100 in Israel on Monday as the conflict between the two countries entered its fourth day.

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.

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.
