IDF says missiles launched from Iran toward Israel
Israel said missiles have been launched from Iran toward Israel.
Sirens are sounding across the country.
Israeli strikes have largely been focused on Beirut's southern suburbs.
Israel continued its intense airstrike campaign across Lebanon, which included several strikes in Beirut's southern suburbs and one in the center of the city.
Israel's Lebanon operation continues as leaders consider their response to Iran's long-range attack on Tuesday, in which hundreds of missiles were fired into the country, according to Danny Danon, Israel's ambassador to the United Nations.
Iran said the unprecedented attack was retaliation for a wave of assassinations carried out by Israel over the last several weeks targeting Hezbollah, including leader Hassan Nasrallah.
Sirens sounded across Israel and some citizens were urged to seek shelter in protected areas. Most of the missiles were intercepted, but "several hits were identified, and the damage is being assessed," an Israeli security official said.
The U.S. fired missiles to help Israel defend itself against the missile attack, according to the Pentagon's Maj. Gen. Pat Ryder.
Israel said missiles have been launched from Iran toward Israel.
Sirens are sounding across the country.
Iran is expected to launch 240 to 250 missiles in two waves at four targets in Israel, including Mossad headquarters and three air bases, according to an Israeli source and a senior U.S. administration official.
Israel is not expected to launch a preemptive strike, according to the U.S. administration official. It should take the missiles less than 15 minutes to reach targets once launched.
The U.S. and Israel have all defenses activated, and Israel will “absolutely “ retaliate after it happens," the official said.
The total number of ballistic missiles is about double the number launched by Iran in April -- 99% of which were intercepted.

The Israel Defense Forces issued a warning for residents of the "Dan area," referring to the greater Tel Aviv area, to stay "near a shelter until further notice."
Sirens sounded in central Israel, the IDF said in a second statement, after issuing the warning to stay in shelters. The sirens sounding in central Israel were due to launches from Lebanon, the IDF told ABC News.
"From this moment, Israelis living in central Israel are advised to stay by their safe rooms. Enter them during sirens and stay there until further notice," IDF spokesperson Daniel Hagari said in Hebrew.

The U.S. Embassy in Jerusalem issued a statement directing all government employees and their family members "to shelter in place until further notice," following reports of an imminent Iranian missile attack on Israel.
The embassy noted the "continued need for caution and increased personal security awareness as security incidents, including mortar and rocket fire and unmanned aircraft system," which it said "often take place without warning."
"The security environment remains complex and can change quickly depending on the political situation and recent events," it added.
