French President Emmanuel Macron has formally announced that he will run for a second term in April's presidential election, ahead of which he is already leading in the polls.

In a "letter to the French" published on domestic media websites, Macron said: "I am seeking your trust again. I am a candidate to invent with you, faced with the century's challenges, a French and European singular response."

The Russian invasion of Ukraine is the largest conflict that Europe has seen since World War II, with Russia conducting a multi-pronged offensive across the country.

The Russian military has pummeled wide areas in Ukraine with airstrikes and has conducted major rocket and artillery bombardments, resulting in large numbers of casualties.

A fire at Europe's biggest nuclear plant ignited by Russian shelling has been extinguished, two people on the site were injured in the fire and Russian forces have taken control of the site.

The head of the United Nations’ atomic watchdog said there has been no release of radiation at the Ukrainian nuclear plant that was targeted.

When Russia launched its war on Ukraine, a Syrian student in the city of Kharkiv joined the exodus of people fleeing the onslaught. It was the third time that 24-year-old Orwa Staif, who grew up in the suburbs of Damascus, was being displaced by war and crises.

For Staif, it was a jarring déjà vu: columns of people, many on foot, carrying what few belongings they could, desperate to escape bombs and missiles. He had seen it all before, in his native Syria.

The walls of Saifullah's home in northern Jakarta are lined like tree rings, marking how high the floodwaters have reached each year -- some more than four feet from the damp dirt floor.

When the water gets too high, Saifullah, who like many Indonesians only uses one name, sends his family to stay with friends. He guards the house until the water can be drained using a makeshift pump. If the pump stops working, he uses a bucket or just waits until the water recedes.

Although Africa has contributed relatively little to the planet's greenhouse gas emissions, the continent has suffered some of the world's heaviest impacts of climate change, from famine to flooding.

Yet from its coral reefs to its highest peaks, the reverberations of human-caused global warming will only get worse, according to a new United Nations report

The moon is about to get walloped by 3 tons of space junk, a punch that will carve out a crater that could fit several semitractor-trailers.

The leftover rocket will smash into the far side of the moon at 5,800 mph (9,300 kph) on Friday, away from telescopes' prying eyes. It may take weeks, even months, to confirm the impact through satellite images.

A hug. A banner. Two simple words written on a pair of shoes: "No war."

Players, fans and teams have not been shy about letting their support for Ukraine, its citizens and its athletes spill onto football fields, rugby pitches and basketball courts across the globe in the wake of Russia's invasion of its neighbor to the west.

"Herders and farmers have their feet on the ground, but their eyes on the sky." The old saying is still popular in Spain's rural communities who, faced with recurrent droughts, have historically paraded sculptures of saints to pray for rain.

The saints are out again this year as large swaths of Spain face one of the driest winters on record. Even as irrigation infrastructure boomed along with industrial farming, the country's ubiquitous dams and desalination plants are up against a looming water crisis scientists have been warning about for decades.

Russians and Belarusians at the Winter Paralympics in Beijing will compete as "neutral athletes" because of their countries' roles in the war against Ukraine, the International Paralympic Committee said Wednesday.

Russian athletes had already been slated to compete as RPC, short for Russian Paralympic Committee, as punishment for the state-sponsored doping scandal at the 2014 Sochi Olympics and a subsequent cover-up.
