President Donald Trump on Monday told reporters he believes the war in Iran "militarily is effectively over," suggesting that — at least for now — he's not prepared to resume the bombardment that has devastated the Islamic Republic and caused reverberations across the global economy.

The president made a surprise visit to the White House briefing room after meeting earlier in the day with Qatar's prime minister, Sheikh Mohammed bin Abdulrahman bin Jassim Al Thani.

Voters have sent a strong election-year message to the new Democratic congressional majority and President Donald Trump: Repair the damage inflation has done to the economy.

Trump, who campaigned on the idea that a Democratic victory in the midterms would trigger a 1929-style economic depression, has maintained that the economy is booming. Since his party lost in Tuesday's voting, he has claimed he is willing to work with Democrats in the House and Senate, though that's not something he has done much of in the past.

Manchester United conceded two goals in less than four minutes against Aston Villa in the Premier League on Sunday to pile more pressure on coach Michael Carrick before his team again rallied.

Barcelona midfielder Fermín López delivered in a big match again, helping the Spanish league leader to come from behind in a 2-1 win at Atletico Madrid on Sunday.

Russia battered Ukraine's power grid again and Ukrainian forces hit another of Russia's biggest oil refineries, officials said Monday, hours before delegations from Moscow and Kyiv were due to meet for new U.S.-brokered talks on how to end the fighting.

Nearly five years after Russia invaded its neighbor, the two countries remain locked in battle with no sign that either side is ready to budge from its demands. The war has already killed hundreds of thousands of soldiers and thousands of civilians, analysts and humanitarian organizations say.

World leaders, delegates and climate activists on Monday will begin negotiations on curbing climate change, which in the last year has led to rising temperatures, deadly heat waves in Europe and beyond, and has played a role in disasters like the devastating floods in Nepal.

This U.N. climate summit, called the Conference of the Parties, or COP31, also comes as the war in Iran has effectively closed the Strait of Hormuz, pushing up global prices of gasoline and oil and myriad products made with them, such as fertilizers and pesticides. The disruption has pushed governments to rethink energy policies, both in the short-term and long-term, including increased investment in renewable energy sources like wind and solar.

For the first time since February, Russian, Ukrainian and U.S. negotiators are scheduled to hold talks on ending the full-scale war that is nearing the five-year mark, with security guarantees topping the agenda.

The two-day session starting Tuesday in Abu Dhabi, United Arab Emirates, follows previous rounds of negotiations early this year that failed to produce any visible progress toward ending Europe's most devastating conflict since World War II.

U.S. Secretary of State Marco Rubio will meet his counterparts from the Group of 7 industrialized democracies on Monday, with unresolved world crises on the agenda and questions about how President Donald Trump will approach foreign policy after his Republican Party's massive losses in the midterm elections.

Two days of talks among the U.S., Britain, Canada, France, Germany, Italy and Japan in Paris coincide with major protests across Europe, including in the French capital.

Young supporters wore his name on their backs like a soccer star's, above the number 27. They sang about brass bands and revolution. Many had spent the fall protesting or blockading their schools.

Then in walked Jean-Luc Mélenchon: 75 years old, on his fourth presidential run and old enough to be their grandfather.

Outdated power grids are a major hurdle in the transition to renewable energy, since older systems often can't absorb all the electricity from new, cleaner sources.

This threatens global efforts to curb climate change by reducing fossil fuels and switching to renewable energy such as solar and wind. At U.N. climate talks kicking off this week, co-hosts Turkey and Australia want more ambitious goals to slash fossil fuels, install renewables and upgrade grids.
