The commander of Iran's Revolutionary Guards on Thursday warned Israel and the U.S. against "miscalculations" in the wake of mass protests, saying the force had its "finger on the trigger".

U.S. President Donald Trump has repeatedly left open the option of new military action against the Islamic republic after Washington backed and joined Israel's 12-day war in June.

Talks to end the war in Ukraine have made "a lot of progress" and are "down to one issue" between Kyiv and Moscow, U.S. special envoy Steve Witkoff said on Thursday ahead of a trip to Russia.

"I think we've got it down to one issue, and we have discussed iterations of that issue, and that means it's solvable. So if both sides want to solve this, we're going to get it solved," Witkoff said at a Ukrainian event on the sidelines of the World Economic Forum in Davos.

Saudi Arabia and eight Muslim-majority countries including Gaza mediators Qatar and Turkey have agreed to join U.S. President Donald Trump's "Board of Peace", the Saudi foreign ministry said on Wednesday.

In a joint statement, Riyadh announced the "shared decision" of the foreign ministers of Saudi Arabia, Qatar, Turkey, Egypt, Jordan, Indonesia, Pakistan, and the United Arab Emirates to join the body to be chaired by Trump, saying they supported his "peace efforts" on the Gaza conflict.

Manchester City were on the wrong side of one of the biggest shocks in Champions League history on Tuesday, while holders Paris Saint-Germain also stumbled but Gabriel Jesus helped keep Arsenal perfect.

U.S. President Donald Trump on Wednesday proclaimed his country was the world's "economic engine," and slammed Europe as "not heading in the right direction," as Washington's allies push back against its bid to seize Greenland.

"The USA is the economic engine on the planet. And when America booms, the entire world booms. It's been the history," he said during a speech at the World Economic Forum in Davos, where the Greenland crisis has dominated talks.

Syria's defense ministry said seven soldiers were killed on Wednesday when the Kurdish-led Syrian Democratic Forces targeted an arms depot in the country's northeast, despite a fresh ceasefire announced a day earlier.

"Army forces found a factory for producing explosive devices and drone munitions" in Hasakeh province near a border crossing with Iraq, the ministry said, adding that as government forces began securing the site, the SDF "targeted it with a suicide drone, leading to an explosion and the death of seven soldiers", with 20 others wounded.

Gaza's civil defense agency said an Israeli strike in the center of the territory on Wednesday killed three journalists, including a freelancer who previously worked for AFP, despite the ceasefire between Israel and Hamas.

In a statement, the civil defense said "the bodies of the three journalists killed in an Israeli air strike in the Al-Zahra area southwest of Gaza City were transported to Al-Aqsa Martyrs Hospital in Deir al-Balah".

U.S. President Donald Trump's government has asked countries to pay up to $1 billion for a permanent spot on his "Board of Peace" aimed at resolving conflicts, according to its charter seen by AFP.

The board was originally conceived to oversee the rebuilding of Gaza, but the charter does not appear to limit its role to the Palestinian territory.

Iran's foreign minister issued the most direct threat yet Wednesday against the United States after Tehran's bloody crackdown on protesters, warning the Islamic Republic will be "firing back with everything we have if we come under renewed attack."

The comments by Abbas Araghchi, who saw his invitation to the World Economic Forum in Davos rescinded over the killings, comes as an American aircraft carrier group moves westward toward the Middle East from Asia. American fighter jets and other equipment appears to be moving in the Mideast after a major U.S. military deployment in the Caribbean saw troops seize Venezuela's Nicolás Maduro.

Russia's interior minister has met with top leaders of ally Cuba in Havana, a show of solidarity after U.S. President Donald Trump warned that the island's longtime communist government "is ready to fall."

Trump this month told Havana to "make a deal," the nature of which he did not divulge, or pay a price similar to Venezuela, whose leader Nicolas Maduro was ousted by U.S. forces in a January 3 bombing raid that killed dozens of people.
