An Israeli strike hit a vehicle in the city of Tyre, south Lebanon on Monday, Lebanese state media reported, as Israel vowed to press attacks on Hezbollah despite Iranian warnings.
Hezbollah meanwhile said it targeted Israeli troops in Lebanon, but did not claim any attacks on Israeli territory.
Lebanon's state-run National News Agency (NNA) reported that "an enemy airstrike targeted a car with a missile in the city of Tyre, near the Lebanese Red Cross building".
An AFP photographer in Tyre saw flames erupting from a car on a coastal road as residents gathered at the scene and an ambulance and paramedics headed towards it.
Reporting airstrikes from the early morning, the NNA said Israeli raids hit more than a dozen locations in the south, including Burj al-Shemali near Tyre.
A Lebanese culture ministry official said Israeli bombardment on the city a day earlier damaged a UNESCO World Heritage site there, and AFP correspondents saw dust and debris at the site.
The NNA said some of Monday's strikes caused casualties, though Lebanon's health ministry has not yet released any tolls.
Iran's military command on Monday afternoon said it was halting its operation against Israel after the two sides exchanged fire for the first time since a truce in the Middle East war took effect in April.
Iran had delivered a "painful response" to Israel and "accordingly, the cessation of armed forces operations is hereby announced", the Khatam al-Anbiya central command said in a statement carried by state television.
"However, it is emphasized that should acts of aggression and hostility continue, including in southern Lebanon, much more severe and crushing measures than before will follow," it added.
But Israeli Defense Minister Israel Katz later vowed that the military would "continue to operate in Lebanon against the terrorist organization Hezbollah".
He added that Israel would strike Beirut's southern suburbs in retaliation for every attack on northern Israel.
"We categorically reject Iran's threats. Any Iranian attempt to link Lebanon and Iran and attack Israel will be met with great force, as happened yesterday," Katz said.
Iran insists a halt to the broader Middle East conflict must include a ceasefire in Lebanon, and on Sunday fired missiles at Israel in response to Israeli strikes on Beirut's southern suburbs earlier in the day.
On Monday, Hezbollah claimed a series of attacks on Israeli troops who have invaded south Lebanon.
Israel's military intercepted three projectiles fired from Lebanon, an AFP correspondent near the border reported, as Israel's military said the munitions had targeted its forces operating in Lebanon's south.
Lebanon says Israeli strikes have killed more than 3,600 people since Hezbollah drew Lebanon into the Middle East conflict on March 2 with rocket fire at Israel to avenge the US-Israeli killing of Iran's supreme leader.
After an April 17 ceasefire between Israel and Hezbollah began, Israel announced a so-called Yellow Line inside Lebanese territory about a dozen kilometers from its northern border where its ground troops are operating.
