US President Donald Trump has largely distanced himself from the Israel-Iran conflict, but has not ruled out the US' direct involvement in the war.

A new wave of missiles launched from Iran were seen in the skies over Tel Aviv, early on Sunday. Sirens sounded in Jersualem and Tel Aviv, as the incoming barrage was intercepted.

At least three people were killed and scores were wounded during an aerial battle over Tel Aviv, as Iranian missiles rained down and Israeli rockets attempted to intercept them.

Aerial attacks between Israel and Iran continued overnight into Monday, marking a fourth day of strikes following Israel's Friday attack. That surprise strike hit the heart of Iran's nuclear program, killing several nuclear scientists as well as high-ranking military leaders, according to Israeli officials.

Israel and Iran have traded more missile attacks despite international calls for a halt to the fighting, with neither country showing signs of backing down as the conflict between the regional foes raged for a third day.
