Lebanon's Hezbollah movement fired heavy rocket barrages at Israel on Sunday, and the Israeli military said houses had been destroyed or set alight near Tel Aviv, after a powerful Israeli airstrike killed at least 29 people in Beirut the day before.
Israel also struck Beirut's Hezbollah-controlled southern suburbs, where intensified bombardment over the last two weeks has coincided with signs of progress in United States-led ceasefire talks.
Hezbollah, which has previously vowed to respond to attacks on Beirut by targeting Tel Aviv, said it had launched precision missiles at two military sites in Tel Aviv and nearby.
Police said there were multiple impact sites in the area of Petah Tikva, on the eastern side of Tel Aviv, and that several people had sustained minor injuries.
The Israel Defense Forces (IDF) said a direct hit on a neighbourhood had left "houses in flames and ruins". Television footage showed an apartment damaged by rocket fire.
The IDF said Hezbollah had fired 240 rockets at Israel, of which many were intercepted, with sirens sounding across most of the country. At least four people had been injured by shrapnel.
The military warned on social media that it planned to target Hezbollah facilities in southern Beirut before strikes that demolished two apartment blocks, according to security sources in Lebanon.
Afterwards, the IDF said it had hit command centres "deliberately embedded between civilian buildings".
On Saturday, it had carried out one of its deadliest and most powerful strikes on the centre of Beirut.
Lebanon's health ministry on Sunday raised the death toll from 20 to 29. It said 84 people had been killed in all on Saturday, taking the death toll to 3,754 since October 2023.
The IDF did not comment on Saturday's strike in the capital or say what it had attacked.
Israel went on the offensive against the Iran-backed Hezbollah in September, pounding the south, the Bekaa Valley and Beirut's southern suburbs with airstrikes after nearly a year of hostilities ignited by the Gaza war.
The Israeli offensive has uprooted more than one million people in Lebanon.
Israel says its aim is to secure the return home of tens of thousands of people evacuated from its north due to rocket attacks by Hezbollah, which opened fire in support of Hamas at the start of the Gaza war in October 2023.
US mediator Amos Hochstein highlighted progress in negotiations during a visit to Beirut last week, before travelling to meet Israeli Prime Minister Benjamin Netanyahu and defence minister Israel Katz, and then returning to Washington.
European Union foreign policy chief Josep Borrell said on Sunday a US ceasefire proposal was awaiting final approval from Israel.
Diplomacy has focused on restoring a ceasefire based on United Nations Security Council Resolution 1701, which ended a 2006 Hezbollah-Israel war. It requires Hezbollah to pull its fighters back around 30km from the Israeli border and the Lebanese army to deploy in the buffer zone.
