Iran's foreign minister said Wednesday that "no tangible progress" has been made in negotiations to end theMiddle Eastwar as fresh US and Iranian strikes strained a fragileceasefire.

Kuwaiti officials said the renewed hostilities included an Iranian drone strike on a passenger terminal atKuwaitinternationalairport that killed one personand wounded 63.

In contrast with the downbeat Iranian remarks, US PresidentDonald Trumpstruck an optimistic note, telling reporters at theWhite Housethat the Irantalkscould yield a result "over the weekend."

"I hear the negotiation itself is going very well actually," Trump said of a potential deal. "It could happen...over the weekend."

Trump also said he wants to separate talks on the conflict inLebanonbetweenIsraeland Iranian-backedHezbollahand those on the war between the United States and Iran, although Tehran insists the two are linked.

"I'd like to separate it, I'd like to have a separate thing, because it is, it is separate," he said.

US Secretary of StateMarco Rubiosaid Iran's highly enricheduraniumstockpiles were at the center of discussions with Tehran and voiced hope that the latest round of talks in Washington between Israel and Lebanon will produce a security roadmap.

Washington insists Tehran must turn over its near-weapons-grade enriched uranium, agree to curb its nuclear activities and re-open theStrait of Hormuz, the keyshippingchannel for Gulf oil and gas, for any peace agreement to take hold.

Iranian Foreign Minister Abbas Araghchi said lines of communication with the United States were still open but warned that any Israeli attack on the Lebanese capitalBeirutas part of its campaign against Hezbollah would trigger a "full-scale resumption" of the conflict.

"Communications with the Americans have not been cut off, and messages have been exchanged regarding the need to stop aggression against Beirut, but no tangible progress has been made in the negotiation process," the Tasnim news agency quoted Araghchi as telling Lebanon's Al Mayadeen TV.

"Any attack on Beirut will have grave consequences and will lead to a full-scale resumption of the war," he said. "Our armed forces are ready to strike Israel if it attacks Beirut."

'Playing with fire'

Kuwait'smilitarycondemned the drone strike on the airport as an act of "criminal Iranian aggression." India's foreign ministry said the one fatality was an Indian national.

Iran's Revolutionary Guards denied attacking the airport and said it was "an error in the American Patriot systems, which landed on the terminal after failing to intercept Iranian missiles." The Revolutionary Guards also accused US forces of provoking a response by targeting a tanker and a communications tower on the country's Qeshm Island.

The fresh attacks constitute one of the more severe tests yet of the April 8 ceasefire that paused more than a month of war sparked by the US-Israeli bombing of Iran, and has largely held despite sporadic exchanges of fire.

Trump played down the renewed hostilities saying "in that part of the world ceasefire is when you're shooting in a more moderate manner."

Israeli Prime MinisterBenjamin Netanyahuaccused Iran meanwhile of "playing with fire."

"Iran surely knows what the (US) president has said, that if necessary, there'll be a full-scale return to military action," Netanyahu said in an interview with US channel CNBC.

Kuwait suspended air traffic and diverted arriving planes to other destinations following the drone attack on the airport, but later restarted Kuwait Airways flights.

The international airport has been targeted several times during the war, and had only fully resumed operations on Monday.

Hassan Sheikh, a 40-year-old Pakistani resident of Kuwait who lives near the airport said he heard explosions throughout the night, adding: "For the first time, mychildrenfelt how serious the situation was."

No partial ceasefire

The escalation came after US, Israeli and Lebanese officials met in Washington for directtalkson ending the parallel conflict between Israel and Hezbollah.

The Lebanese embassy in Washington said a US proposal to stop attacks would at first only cover Israeli strikes on Beirut and Hezbollah attacks on Israeli territory.

Neither side has publicly accepted the deal, and senior Hezbollah official Mahmud Qomati told AFP the group "will not accept a partial ceasefire."

Israeli troops are staging their deepest ground offensive into Lebanon in two decades.

Lebanon said Israeli strikes on Wednesday killed at least nine people in the country's south, including two paramedics, while another raid hit a car near Beirut.

Hezbollah claimed a rocket attack on Wednesday that targeted troops in northern Israel, saying it was responding to Israeli ceasefire violations.

Atruceto halt the fighting in Lebanon was meant to take hold on April 17 but has never been observed.
