Iran said Friday that in order to reach a deal, the United States will have to drop its "excessive demands", tempering the optimism expressed after talks seen as a last-ditch bid to avert war.

The Oman-mediated talks follow repeated threats from President Donald Trump to strike Iran, and with the United States conducting its biggest military build-up in the region in decades.

Iran and the United States held hours of indirect negotiations Thursday over Tehran's nuclear program but walked away without a deal, leaving the danger of another Mideast war on the table as the U.S. has gathered a massive fleet of aircraft and warships in the region.

Oman's Foreign Minister Badr al-Busaidi, who mediated the talks in Geneva, said there had been "significant progress in the negotiation" without elaborating.

Pakistan's defense minister early Friday said that his country had run out of "patience" and now considers itself in an "open war" with neighboring Afghanistan after both sides launched strikes following what Islamabad described as an Afghan cross-border attack.

In a post on X, Defense Minister Khawaja Mohammad Asif said Pakistan had hoped for peace in Afghanistan after the withdrawal of NATO forces and expected the Taliban to focus on the welfare of the Afghan people and regional stability. Instead, he alleged, the Taliban had turned Afghanistan "into a colony of India," gathered militants from around the world and begun "exporting terrorism."

Iran's Foreign Minister Abbas Araghchi said Thursday that the latest round of talks with the United States dealt with the nuclear program and the lifting of sanctions, adding that negotiators made "good progress".

"We made very good progress and entered into the elements of an agreement very seriously, both in the nuclear field and in the sanctions field," Araghchi told state TV after the talks in Geneva ended.

U.S. and Ukrainian officials were meeting in Geneva on Thursday to discuss advancing efforts to end Russia's four-year invasion of Ukraine, just as Moscow signaled it was in no hurry to sign a deal.

Cuba will defend itself against any "terrorist aggression," President Miguel Diaz-Canel declared Thursday, a day after a deadly shoot-out between gunmen on a U.S.-registered speedboat and Cuban coast guard vessels.

"Cuba will defend itself with determination and firmness against any terrorist and mercenary aggression against its sovereignty and national stability," the president said on X, denouncing Wednesday's confrontation as an attempted "infiltration."

Danish Prime Minister Mette Frederiksen on Thursday called an early general election for March 24, as the country digests a standoff with U.S. President Donald Trump, who has designs on Greenland, a semiautonomous territory of Denmark.

Voters in the Scandinavian country, a NATO and European Union member, will determine who sits in the Folketing, or parliament. It has 179 seats — 175 of which go to lawmakers representing Denmark and two apiece to lawmakers from Greenland and the kingdom's other semiautonomous territory, the Faroe Islands.

As U.S. forces mass in the Middle East, Iran faces the threat of major strikes by the world's most powerful military, potentially targeting its leaders, military, nuclear sites and critical infrastructure.

Iran has nowhere near the same capabilities, and is even more vulnerable after last year's war launched by Israel and recent anti-government protests. But it could still inflict pain on American forces and allies, and may feel it has to if the Islamic Republic's survival is at stake.

Former Secretary of State Hillary Clinton is testifying before U.S. House lawmakers in New York on Thursday as part of a congressional investigation into convicted sex offender Jeffrey Epstein, starting off two days of depositions that will also include former President Bill Clinton.

The closed-door depositions in the Clintons' hometown of Chappaqua, a typically quiet hamlet north of New York City, come after months of tense back-and-forth between the former high-powered Democratic couple and the Republican-controlled House Oversight Committee. It will be the first time that a former president has been forced to testify before Congress.

Iran and the United States were holding another round of indirect talks in Geneva on Thursday to try to reach a deal on Tehran's nuclear program and potentially avert another war as the U.S. gathers a massive fleet of aircraft and warships in the Middle East.

U.S. President Donald Trump wants a deal to constrain Iran's nuclear program, and he sees an opportunity while the country is struggling at home with growing dissent following nationwide protests. Iran also hopes to avert war, but maintains it has the right to enrich uranium and does not want to discuss other issues, like its long-range missile program or support for armed groups like Hamas and Hezbollah.
