The retaliatory strikes came on Saturday, a day after Israel killed top Iranian military leaders and scientists and destroyed an aboveground nuclear enrichment plant near Natanz.

In one of the heaviest strikes, about 40 Iranian missiles targeted the northern port city of Haifa on Sunday and a number of missiles breached air defences and struck Tel Aviv. Nearby in Bat Yam, a missile destroyed part of an apartment block, killing a nine-year-old girl, a 10-year-old boy, and two elderly women.

Israel's attack on Iran raises questions like whether the US will get involved, how Iran will respond, and if a wider conflict may be triggered.

National security experts warn that Israel's attack on Iran shows why Chinese land and asset purchases in the U.S. pose a significant threat to American security.

Israel launched massive airstrikes on Iranian nuclear and military targets; Iran responded with over 100 drones. U.S. denies involvement.

The U.S. military is helping intercept missiles that Iran fired in retaliation at Israel, a U.S. official says.
