Yemen's Iranian-backed Houthi rebels threatened new attacks on ships traveling through the Red Sea corridor, likely trying to back Iran as it worried Monday about an approaching U.S. aircraft carrier after President Donald Trump threatened military action over its crackdown on nationwide protests.

A short video by the Houthis included previously published images of a ship on fire, with the caption: "Soon." The rebels did not elaborate, but their campaign in the Red Sea saw over 100 ships attacked as part of a campaign the Houthis said pressured Israel over its war against Hamas in the Gaza Strip. The Houthis halted their fire after a ceasefire in the conflict, though they've repeatedly warned they could resume fire if needed.

The Kremlin on Monday said the US-brokered trilateral talks in the UAE between Russian and Ukrainian negotiators had been held in a "constructive spirit" but that there was still "significant work ahead".

"It would be a mistake to expect any significant results from the initial contacts... But the very fact that these contacts have begun in a constructive spirit can be viewed positively. However, there is significant work ahead," Kremlin spokesman Dmitry Peskov told journalists.

Israel said its military was conducting a "large-scale operation" to locate the last hostage in Gaza, as Washington and other mediators pressure Israel and Hamas to move into the next phase of their ceasefire.

The statement came Sunday as Israel's Cabinet met to discuss the possibility of opening Gaza's key Rafah border crossing with Egypt, and a day after top U.S. envoys met with Prime Minister Benjamin Netanyahu about next steps.

Iran's paramilitary Revolutionary Guard, a force which was key in putting down recent nationwide protests in a crackdown that left thousands dead, is "more ready than ever, finger on the trigger," its commander said Saturday, as U.S. warships headed toward the Middle East.

Senegal coach Pape Thiaw has defended his team's walkoff during the Africa Cup of Nations final, saying it was an emotional decision taken in the chaos of the moment.

The European Union is willing to implement a sweeping free trade agreement with the Mercosur group of South American countries on a provisional basis, the head of the EU's executive commission said Friday, despite a vote by the EU parliament to delay ratification for legal review.

Leading global economic policymakers at the World Economic Forum in Davos urged countries and businesses to filter out the turmoil from a week of clashes with the Trump administration and focus on boosting growth and fighting inequality in a world where trade will continue to flow and international cooperation is still badly needed.

The global economy is showing unexpected resilience despite the noise, European Central Bank head Christine Lagarde, International Monetary Fund head Kristalina Georgieva and World Trade Organization head Ngozi Okonjo-Iweala said in a panel discussion. But while growth is holding up, troubles like worrisome levels of government debt and inequality loom.
