The Iranian regime faces pressure as Israel strikes military targets, with Iranian Americans advocating for the overthrow of what one Iranian American describes as a "paper tiger regime."

Investors have been weighing the odds of further escalation in the conflict and spillover into the broader oil-rich Middle East.

TEL AVIV, Israel (AP) — Iran fired a new wave of missile attacks on Israel early Monday, killing at least five people, while Israel claimed in the fourth day of the conflict that it had now achieved “aerial superiority” over Tehran and could fly over the Iranian capital without facing major threats.

At least 24 people have been killed in Israel as Iran launched retaliatory airstrikes targeting civilian areas. A U.S. Embassy branch in Tel Aviv suffered minor damage.

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'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.

It follows daytime attacks from both sides, with Israeli strikes in Tehran continuing and Iran firing more missiles towards Israel.

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

Iran and Israel continued trading missiles and airstrikes on June 14, a day after Israel launched a sweeping air offensive against its old enemy.

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