The Israeli Defence Forces (IDF) have bombed the Qasmiya Bridge in southern Lebanon, a key crossing that links the country's south to the rest of the nation.
According to Lebanon's state-run National News Agency (NNA), three strikes on the bridge near Tyre caused extensive damage, rendering it unusable.
Lebanese President Joseph Aoun warned that the bridge attacks represent a dangerous escalation and flagrant violation of Lebanon's sovereignty.
Israeli Defence Minister Israel Katz ordered the IDF to destroy more bridges over the Litani River used by Hezbollah in south Lebanon and to step up the demolition of houses.
The Israeli military announced it is expanding its ground campaign against Hezbollah in Lebanon, warning of a lengthy operation.
Lebanon was pulled into the Middle East war when Hezbollah began firing rockets into Israel on March 2 to avenge the killing of Iran's supreme leader, Ayatollah Ali Khamenei.
