Live: Israel ramps up strikes on Gaza after Iran attack

Iran's Revolutionary Guard Corps said in a statement that they fired tens of missiles at Israel.

The IRGC said the attack was in retaliation for the killing of Hamas's leader, Ismail Haniyeh, in Tehran, Hezbollah leader Hassan Nasrallah and IRGC commander Abbas Nilforoushan, who was killed last week along with Nasrallah. 

The IRGC said it would target Jerusalem again if Israel retaliates. 

Israeli media is reporting a direct hit on a building in northern Tel Aviv from an Iranian strike.

Missiles are also falling in Negev and Sharon, the details are under investigation.

Explosions are being reported in Tel Aviv, in what appears to be a second wave of the Iranian attack. 

Israel's air defence system is engaging the missiles. 

Explosions and air-raid sirens are being reported across Jerusalem, according to a western official. 

It's unclear if the explosions are interceptions from Israel's air defence system.

Iran has launched 102 missiles at Israel with sirens sounding from Jerusalem to Tel Aviv.

Missiles are raining down on Tel Aviv, according to live video footage.

Flares in the sky can be seen and loud explosions heard. 

Iran has launched missiles at Israel, the Israeli military said.

Houthi military spokesperson Yahya Saree took credit for the attacks, which come amid rising tensions in the region. 

Oil prices jumped about 3 percent on Tuesday after the White House warned that Iran is preparing to launch a missile attack against Israel.

Oil prices shrugged off Israel's invasion of Lebanon and killing of Hezbollah chief Hassan Nasrallah last week, but the spectre of an Iranian attack risks bringing the Middle East to the brink of a regional war. 

Stock markets are also down on geopolitical tensions. 

Iran is expected to attack Israel in the coming hours and target three military bases and an intelligence headquarters north of Tel Aviv, the New York Times reported.

Three Israeli officials told the NYT that the intelligence centre has been evacuated.

The officials calculate that the ballistic missiles will reach Israel in 12 minutes once fired, and that cruise missiles will arrive within two hours. They also expect Iran to fire drones. 

The Qassam Brigades, the armed wing of Hamas, has claimed attacks on Israeli military vehicles and troops in central and southern Gaza.

The group said it fired al-Yassin 105 rockets at a Merkava tank and two D9 military bulldozers in the al-Fukhari area in the east of Khan Younis city.

The group also claimed it fired rockets and mortar shells at Israel forces in the Netzarim Corridor in central Gaza.

The US warned its diplomats in Israel to shelter in place and prepare to go to bomb shelters after it warned that Iran is preparing to launch a ballistic missile attack on Israel, a US official in the region told Middle East Eye. 

The US has deployed additional forces to the region amid Israel's invasion of Lebanon. 

The Israeli air raids we reported on previously struck two areas in Beirut, according to Lebanon's state-run National News Agency.

The agency reported a "violent enemy strike" targeting a building in Jnah, near the Zahraa Hospital in the Dahiyeh neighbourhood, not far from where thousands of displaced people were sheltering.

The second strike hit a building near the Kuwaiti embassy.

The Israeli military claimed its fighter jets had conducted "a precise strike in Beirut."
