EU chief Ursula von der Leyen on Friday proposed a new round of sanctions on Moscow over the Ukraine war, including a ban on providing services for tankers carrying Russian crude oil.

The package, meant to be approved for the fourth anniversary of Moscow's invasion, on February 24, also targets Russian banks, cryptocurrency traders and metal exports.

The United States on Friday urged three-way talks with Russia and China to set new limits on nuclear weapons, after the last treaty between top nuclear powers Washington and Moscow expired.

Thomas DiNanno, the under secretary of state for arms control, told the Conference on Disarmament in Geneva that "serial Russian violations, growth of more worldwide stockpiles and flaws in New Start's design and implementation gives the United States a clear imperative to call for a new architecture that addresses the threats of today, not those of a bygone era".

The Kremlin said Friday that two days of talks with Ukraine, mediated by the United States, on how to find a possible end to the war were difficult but "constructive", saying that they will continue.

"For two days there was constructive and very difficult work," Kremlin spokesman Dmitry Peskov told reporters a day after the Abu Dhabi negotiations ended, adding: "they will continue."

French Foreign Minister Jean-Noel Barrot said Friday that Lebanon's army must be given the means to disarm militant group Hezbollah and replace a United Nations peacekeeping force after its mandate ends this year.

On the final stop of a regional tour that has taken him to Syria and Iraq, Barrot was meeting senior officials in Beirut on Friday, with discussions expected to address preparations for a March conference in Paris in support of the Lebanese army.

"They drove us out at gunpoint," says Lebanese citizen Zeinab Qataya, who fled her adopted home in Syria after the fall of Bashar al-Assad and returned to her country to live in a camp built by Hezbollah.

The construction of the Imam Ali Housing Compound has proved controversial, but Lebanese and Syrian families pushed out of villages just over the border in Syria say they now rely on the Iran-backed movement for safety.

Top U.S. military officer General Dan Caine met with Rodolphe Haykal this week, a spokesman said Thursday, after a previously planned visit by the Lebanese army commander to Washington was scrapped.

Caine held talks with Haykal on Tuesday and Qatar's defense chief the day before, "reaffirming the importance of the United States' enduring defense relationships in the Middle East," U.S. Joint Staff spokesman Joseph Holstead said in a statement, without providing further details.

Spanish rescuers on Thursday desperately searched for a woman missing after a new storm hit the Iberian peninsula while Portugal warned of a heightened flood risk after several months' worth of rain fell in a few hours.

One death has already been confirmed in Portugal from the seventh storm to hit the peninsula this year. Portugal has barely recovered from a battering by rain and winds last week that killed five people, injured hundreds and left tens of thousands without power.

Keir Starmer vowed Thursday to remain Britain's prime minister despite a storm over his appointment last year of disgraced politician Peter Mandelson, linked to late U.S. sex offender Jeffrey Epstein, as Britain's envoy to Washington.

"I intend to go on doing that vital work for our country because I believe it is the absolute focus and of first importance for this government," he told reporters, after apologizing to the victims of Epstein for believing Mandelson's "lies" about their ties.

Ukraine and Russia have conducted their first prisoner exchange in months, each releasing 157 captured soldiers, Russia's defense ministry said Thursday, amid U.S.-brokered talks in Abu Dhabi aimed at ending the war.
