Blinken says US wants Lebanon solution, not 'broader conflict'

US Secretary of State Antony Blinken voiced hope on Friday for a diplomatic solution in Lebanon and preventing a broader conflict in the region.

Blinken however, said that Israel, which has been carrying out deadly strikes on Lebanon, "has a right to defend itself" against Hezbollah, but said he was alarmed by the worsening humanitarian situation.

The US is Israel's key alley, and has supplied billions of dollars worth of weapons used amid its onslaughts in Gaza and Lebanon.

"We continue to engage intensely to prevent broader conflict in the region," Blinken told reporters after an East Asia Summit in Laos.

"We all have a strong interest in trying to help create an environment in which people can go back to their homes, their safety and security, kids can go back to school," he said.

"So Israel has a clear and very legitimate interest in doing that. The people of Lebanon want the same thing. We believe that the best way to get there is through a diplomatic understanding, one that we've been working on for some time, and one that we focus on right now."

Later in the day Blinken spoke by phone with Lebanese Prime Minister Najib Mikati and parliament speaker Nabih Berri, according to a statement from the US State Department.

Lebanon's presidency has been vacant for two years, and Blinken stressed the "the need to empower leadership that reflects the will of the people for a stable, prosperous, and independent Lebanon".

He said that "Lebanon cannot allow Iran or Hezbollah to stand in the way of Lebanon's security and stability".

The statement did not mention discussions on a possible ceasefire between Israel and Hezbollah, with whom it has been engaging in daily cross-border fire since October last year amid the war in Gaza. The violence was then followed by an expansion of operations in Lebanon, which included the explosion of a number of walkie-talkies and pagers, the killing of Hezbollah commander Ibrahim Aqil and strikes on September 23 which killed more than 500 people.

Blinken said the United States would work to support the Lebanese state to build itself up after Hezbollah's long-held sway.

"It's clear that the people of Lebanon have an interest - a strong interest - in the state asserting itself and taking responsibility for the country and its future," he said.

He also said that the United States was voicing concern directly to Israel on the humanitarian situation in Gaza, where a year-long indiscriminate bombing campaign has been ongoing.

"I have real concern about the inadequacy of the assistance that's getting to them," Blinken said, adding that the United States has been "very directly engaged with Israel" on the topic.

At least 42,175 people have been killed by Israeli bombing in Gaza, while over 2,100 have been killed in Lebanon.
