U.N. refugee chief Filippo Grandi said an Israeli air strike hit "humanitarian structures" Saturday at a border crossing between Lebanon and Syria that was previously hit last month.

Israeli naval commandos have seized a trainee mariner an Israeli military official described as a "senior operative" of Hezbollah in a raid in Lebanon and brought him to Israel for questioning.

A Bangladeshi worker died in a air strike in Lebanon, Dhaka's foreign ministry said Sunday, as the Israeli bombardment hampered efforts to repatriate citizens.

The foreign ministry estimates that between 70,000 and 100,000 of its nationals are working in Lebanon, many as laborers or domestic workers.

Lebanon's health ministry said one person was killed and 15 people were wounded Saturday in an Israeli strike on the Galerie Semaan area on the outskirts of Beirut's southern suburbs.

A 25-strong Israeli naval force made a landing on Batroun's shore at dawn Friday and abducted Hezbollah official Imad Fadel Amhaz from a chalet, media reports and security sources said on Saturday.

"Israeli Navy SEALs captured last night Imad Amhaz -- a senior member of Hezbollah's naval force -- in an operation in Northern Lebanon," an Israeli official told U.S. news portal Axios.

The United Nations has warned its flash appeal for humanitarian aid in Lebanon was so far only 17 percent funded, urging donor countries to turn pledges into cash.

Minutes from the heart of Beirut, the Lebanese capital's once vibrant southern suburbs lie largely deserted save for black-clad Hezbollah militants standing guard amid the rubble.

A missile strike in Israel's Sharon area wounded 19 people, police said early Saturday, after the army reported three projectiles were fired from Lebanon into central Israel.

Hezbollah said on Saturday it had launched rockets at an Israeli intelligence base near Tel Aviv in the early hours of Saturday.

At 2:30 AM (00:30 GMT), fighters "fired a salvo of rockets at the Glilot base of the 8200 military intelligence unit in the suburbs of Tel Aviv," the group said in a statement.

The U.N. peacekeeping chief says the U.N. force in southern Lebanon is determined to stay, not only because of its mandate monitoring attacks by Israel and Hezbollah but because the departure of peacekeepers would likely mean U.N. facilities would be taken over by one of the warring parties.

“That would be very bad for many reasons, including the perception of impartiality and neutrality of the United Nations,” Jean-Pierre Lacroix said in a U.N. interview.
