WATCH: Tel Aviv homes devastated by Iranian missile strike

Several homes were reduced to rubble and buildings were damaged when an Iranian missile struck a Tel Aviv neighbourhood on Sunday (June 22), hours after Donald Trump said the U.S. had "obliterated" Tehran's key nuclear sites, joining Israel in the biggest Western military action against the Islamic Republic since its 1979 revolution.

Tehran vowed to defend itself and responded with a volley of missiles at Israel that wounded scores of people and destroyed buildings in its commercial hub.

At least 18 people were wounded in Tel Aviv, Israeli media reported.

Israeli President Isaac Herzog, who arrived at the scene with Tel Aviv Mayor Ron Huldai, thanked Trump and hailed the U.S. assault as "a historic resolution which can change the entire trajectory of the Middle East."

Iran, which has responded to Israel's sudden blitz on its nuclear and military apparatus since June 13 with missile fire on Israeli cities, called the U.S. attack a grave violation of international law that would have "everlasting consequences."

Iranian authorities say over 400 people have been killed since Israel's attacks began, mostly civilians. In Israel, at least 24 civilians have been killed, according to local authorities.
