Iran on Tuesday launched a major missile attack on Israel, firing scores of rockets as air raids have sounded off in all parts of the country.

Sounds of explosions were heard in the cities of Tel Aviv and Jerusalem, and sirens all over the country have been blaring. The Israeli military has instructed Israeli citizens to head to protected areas and bomb shelters.

The attack comes several days after Israel killed Hezbollah leader Hassan Nasrallah in a massive strike on southern Beirut, and comes amid Israeli cross-border raids into Lebanon.

Israel has closed its airspace following Iran’s strikes.

Pictures and videos show the skies of Tel Aviv being lit up with rocket fire, and videos seem to show some missiles making direct hits with smoke visible.

Iran’s Islamic Revolutionary Guard Corps (IRGC) said in a statement that Tehran launched tens of missiles towards Israel, adding that Israel would again be targeted with strikes if it retaliates.

The IRGC said that the missile attack was in response to Israel’s killing of Nasrallah and IRGC commander Abbas Nilforoushan in Beirut, as well as Israel’s killing of Hamas leader Ismail Haniyeh in Tehran in July.

“We attacked the heart of occupied lands. If the Zionist regime tries to respond to the Iranian operation it will face crushing responses,” the IRGC said in its statement.

Immediately after the attack, US President Joe Biden and Vice President Kamala Harris attended a national security briefing.

US Secretary of Defence Lloyd Austin also spoke with his Israeli counterpart Yoav Gallant on Tuesday, and the two military leaders spoke of “severe consequences” for Iran if it launched a direct attack on Israel.

So far, the attack has already appeared to have caused more damage to Israel than the previous Iranian attack in April, when hundreds of armed drones were launched in retaliation for the Israeli attack on the Iranian consulate building in Damascus.

Most of the drones in that attack were intercepted by Israel, working in tandem with the US, France, and other countries including Jordan.

In this attack, reports have stated that Iranian missiles have been flying over Jordan and some have been intercepted over Jordan.
