The attacks took place near Jiyeh, about 20 kilometres (12 miles) south of the capital, Lebanon's National News Agency said, without specifying if there were casualties.

An AFP photographer saw a burned-out car in the middle of the road and rescuers carrying a body.

On Saturday, similar strikes targeted two other cars in the same area.

Israel has kept up airstrikes in Lebanon against the Iran-backed militant group Hezbollah despite a truce since April 17 aimed at halting the fighting.

On Tuesday, 13 people were killed in attacks on towns in the south, according to Lebanon's health ministry, which said a total of 380 people had been killed since the start of the ceasefire.

On Wednesday the Israeli military also issued new evacuation warnings for six villages in the Tyre region in anticipation of fresh attacks.

The violence came with Lebanon and Israel due to hold a new round of direct negotiations in Washington on Thursday, brokered by the United States.

Hezbollah, which has been launching attacks on northern Israel as well as Israeli troops who have entered and occupied a section of southern Lebanon, says it opposes the negotiations in the US.

On Tuesday, its leader Naim Qassem warned that he would turn the battlefield into "hell" for Israel.

Since Hezbollah dragged Lebanon into the wider regional war in early March, more than 2,800 people have been killed in the country, including 200 children, according to the health ministry.
