A resolution to end US support for Israel's war in Lebanon was met with a rebuke from most Democrats in the House of Representatives late Thursday, as a total of 324 lawmakers from both sides of the aisle rejected it, and only 92 voted in support.

Key to Iran agreeing to any deal for nuclear concessions and the full reopening of the Strait of Hormuz, as US President Donald Trump has demanded, is a ceasefire in Lebanon.

On Thursday, Michigan Democratic Congresswoman Rashida Tlaib forced a vote on her war powers resolution to end US participation in what she called "the genocidal war on Lebanon", given Washington's logistical and intelligence support to Israel, including the sale of weapons.

"Since early March, Israel’s military has murdered more than 3,500 people in Lebanon, including 128 paramedics and healthcare workers. The Israeli military has focused on bombing ambulances, medical facilities, and homes - forcibly displacing 20 percent of the population," she said in a statement.

"These are all war crimes."
