Lebanon's Hezbollah expressed solidarity with Iran on Saturday as it came under attack from the United States and Israel, warning in a statement of dire consequences for the region without saying whether it would get involved.
Israel had warned Beirut that it would strike Lebanon hard, targeting civilian infrastructure including the airport, if Hezbollah involved itself in any US-Iran war.
In a statement, Hezbollah said the consequences of the US-Israeli plan would "affect everyone without exception if left unchallenged.”
"We are confident that the American and Israeli enemy will receive a major blow," it said.
Israel's military said on Saturday that it carried out strikes on Hezbollah infrastructure in south Lebanon.
