Iran said on Sunday that the ongoing conflict in Lebanon between Israel and Hezbollah will top the agenda in talks with the United States in Switzerland, as well as issues such as frozen Iranian funds and the sale of the country's oil.

The Israeli military said that one of its soldiers was killed in fighting in southern Lebanon on Saturday, marking the fifth such fatality since a U.S.-Iran deal was reached to end the Middle East war.

Lebanon's central bank on Saturday condemned a "direct and deliberate" Israeli attack on one of its branches in the southern city of Nabatieh, where Israel had intensified its strikes despite a ceasefire.

Cautious calm has been engulfing south Lebanon since Saturday, after Israel's political leadership ordered its army to cease its operations, reportedly following intense U.S. pressure to do so.

Italian Prime Minister Giorgia Meloni fired back at U.S. President Donald Trump on Saturday, saying his "constant, unprovoked attacks are senseless" after he escalated a diplomatic row by accusing her of repeatedly seeking a photograph with him.

U.S. President Donald Trump warned that the United States could impose tolls on the vital Strait of Hormuz waterway if negotiators are unable to complete a deal to end the war in Iran.

There will be no tolls "unless they are imposed by and for the United States of America, should the deal not be completed, for services rendered as the Guardian Angel to the countries of the Middle East for purposes of both past, present, and future reimbursement of costs," Trump posted on Truth Social.

U.S. Vice President JD Vance expressed hopes on Sunday of turning a "new leaf" during talks with Iran in Switzerland, even as the threat of renewed fighting in Lebanon and lack of consensus on key issues rendered prospects for a permanent deal elusive.

Pakistan said technical talks to implement the U.S.-Iran deal to end the Middle East war would be held in Switzerland on Sunday.

Activists and campaign groups on Saturday paid tribute to Lebanese environmentalist Mona Khalil who died from injuries sustained in an Israeli strike in the country's south, where she dedicated her life to turtle conservation for decades.

Iran said it was once again closing the vital Strait of Hormuz shipping lane on Saturday over Israel's attacks in Lebanon, calling them a violation of its deal with the United States to end the Middle East war.
