Hezbollah said it launched “a salvo of Fadi 1 rockets” targeting the Carmel military base near Haifa. Israel Defense Forces said they spotted five missiles coming toward the city and tried to shoot them down, but most of them landed. Of the injured, one person had light to moderate injuries while the four others suffered light injuries from shrapnel.

The IDF said Hezbollah launched over 120 missiles across the border on Sunday, one day before the anniversary of Oct. 7, the Hamas terrorist attack that prompted the war in Gaza and has since expanded into a wider Middle Eastern conflict.

Israel has recently targeted Lebanon and launched strikes on Sunday targeting Hezbollah’s intelligence headquarters, a weapons storage facility, and other sites in the capital city of Beirut. Earlier this weekend, the heir-apparent to Hassan Nasrallah, Hezbollah’s longtime leader who was assassinated by Israel in late September, has been out of contact with Lebanese security forces following an Israeli strike on a suburb south of Beirut.

All eyes are on Israel as it weighs a response to the Iranian missile attack on Oct. 1, in which the Arab country launched roughly 180 missiles at Israel. Most of those missiles were shot down by Israeli air defense systems or U.S. Navy destroyers. Israeli Prime Minister Benjamin Netanyahu said after the attack that Tehran will “pay” and Israel “will keep to the rule we have determined: Whoever attacks us — we attack them.”

National security experts have pointed to Iran’s nuclear facilities, oil production facilities, and air defense systems as possible targets depending on how strongly Israel wants to retaliate.

On Oct. 3, President Joe Biden suggested he doesn’t support such an attack, saying he would consider “other alternatives” if he was in Netanyahu’s position.

“If I were in their shoes, I’d be thinking about other alternatives than striking oil fields,” Biden said during a rare appearance at a White House daily press briefing.

Iran’s Civil Aviation Organization originally canceled all flights from Sunday night into Monday morning due to “operational restrictions that have arisen” and said parts of its airspace would be closed for “military exercises.” That was reversed late on Sunday and flights have resumed.
