Israel has carried out more air strikes in Beirut and southern Lebanon, including on branches of a bank linked to Hezbollah.
Explosions were heard in southern Beirut's Dahieh district, an area controlled by Hezbollah, as well as the Bekaa Valley and southern Lebanon. It is unclear whether there are any casualties.
The Israeli military earlier warned people living in more than 20 areas in Lebanon – including 14 in the capital Beirut – that it planned to carry out strikes throughout the night.
The Israel Defense Forces (IDF) also said it would target banks and other financial infrastructure supporting Hezbollah.
In a statement on Sunday evening, IDF spokesman Rear Adm Daniel Hagari warned that "anyone located near sites used to fund Hezbollah’s terror activities must move away from these locations immediately".
"We will strike several targets in the coming hours and additional targets throughout the night," he said.
"In the coming days, we will reveal how Iran funds Hezbollah's terror activities by using civilian institutions, associations, and NGOs that act as fronts for terrorism," the Israeli spokesman added.
Lebanon's state-run news agency NNA reported strikes on branches of the bank Al-Qard Al-Hassan association, including in the eastern Bekaa Valley.
It also reported a strike on the bank's branch near Rafic Hariri International Airport in Beirut. Footage showed smoke billowing following a blast near the airport.
The bank has more than 30 branches across Lebanon, including two in central Beirut.
Israel accuses the association of funnelling Iranian money to the group to fund buying and storing weapons and to pay the salaries of its members. The institution has been under US sanctions since 2007, and is accused by American officials of being a cover for Hezbollah to manage its financial activities.
It also offers services to civilians in parts of the country where the group has strong support.
Meanwhile, Hezbollah said it had fired more rockets into Israel on Sunday, targeting military bases. It also said it fired at Israeli troops on the ground in southern Lebanon.

It also said that its warplanes conducted "an intelligence-based strike on a command centre of Hezbollah's intelligence headquarters and an underground weapons workshop in Beirut".
It said steps had been taken to "reduce the possibility of civilian casualties".
Israel has been accused by Hezbollah and Lebanese officials of targeting civilians, which it denies.
On Sunday, the United Nations Interim Force in Lebanon (Unifil) accused the IDF of deliberately demolishing an observation tower and perimeter fence of a UN position in the southern Lebanese town of Marwahin on the border with Israel. It follows similar incidents in recent weeks.
"Yet again, we note that breaching a UN position and damaging UN assets is a flagrant violation of international law and Security Council resolution 1701," the Unifil said in a statement.
