Iran's foreign minister said on Wednesday (3) that "no tangible progress" has been made in negotiations to end the Middle East war as fresh US and Iranian strikes strained a fragile ceasefire.

Kuwaiti officials said the renewed hostilities included an Iranian drone strike on a passenger terminal at Kuwait International Airport that killed one person and wounded 63.

In contrast with the downbeat Iranian remarks, US President Donald Trump voiced optimism again, telling reporters at the White House "it could happen ... over the weekend."

"I hear the negotiation itself is going very well, actually," Trump said of the latest bid to end the US-Israeli war in the Middle East, which began on Feb 28.

However, US lawmakers dealt a political blow to the Republican president on Wednesday when the House of Representatives passed a resolution directing the withdrawal of American troops from the Iran war.

The resolution, adopted with four Republican members joining the Democrats, was largely symbolic, as the US president can veto the measure if it gains Senate approval.

"This is a loud and unambiguous message to Donald Trump on behalf of the American people: it’s time to end his deeply unpopular and illegal war of choice in Iran,” Democrats posted on X.
