Iran on Sunday once again denied aiding Yemen's Houthi rebels after the United States launched a wave of airstrikes against them and President Donald Trump warned that Tehran would be held "fully accountable" for their actions.

The Houthi-run Health Ministry said the strikes killed at least 31 people, including women and children, and wounded over 100. The rebels said one strike hit two homes in northern Saada province, killing four children and a woman. The rebel-run Al-Masirah TV showed images of what it said were the bodies.

Russia and Ukraine traded heavy aerial blows overnight Saturday, with both sides reporting more than 100 enemy drones over their respective territories.

The attack comes less than 24 hours after Russian President Vladimir Putin met with U.S. envoy Steve Witkoff to discuss details of the American proposal for a 30-day ceasefire in the war with Ukraine,

More than 50 universities are being investigated for alleged racial discrimination as part of President Donald Trump's campaign to end diversity, equity and inclusion programs that his officials say exclude white and Asian American students.

The Education Department announced the new investigations Friday, one month after issuing a memo warning America's schools and colleges that they could lose federal money over "race-based preferences" in admissions, scholarships or any aspect of student life.

Russian President Vladimir Putin met with U.S. envoy Steve Witkoff to discuss details of the American proposal for a 30-day ceasefire in the war with Ukraine, asking him to convey Moscow's thoughts to Washington, Kremlin spokesman Dmitry Peskov said Friday.

Putin asked Witkoff late Thursday to give additional messages to U.S. President Donald Trump, Peskov told reporters, after the Russian leader said at a news conference that he supported a truce in principle but set out a host of details that need to be clarified before it is agreed.

Demonstrators from a Jewish group filled the lobby of Trump Tower on Thursday to denounce the immigration arrest of Mahmoud Khalil, a pro-Palestinian activist who helped lead protests against Israel at Columbia University.

The demonstrators from Jewish Voice for Peace wore red shirts reading "Jews say stop arming Israel" and held up banners as they chanted "Bring Mahmoud home now!" on the lower level of the Fifth Avenue building's public atrium.

Representatives of China, Russia and Iran called Friday for an end to U.S. sanctions on Iran over its rapidly advancing nuclear program and a restart to multinational talks on the issue.

The talks are the latest attempt to broach the matter and come after U.S. President Donald Trump wrote to Iran's supreme leader in an attempt to jumpstart talks.

Belgian federal prosecutors said Thursday they have arrested several individuals as part of a corruption probe linked to the European Parliament amid reports in local media that Chinese company Huawei bribed EU lawmakers.

Some 100 federal police officers carried out 21 searches in Brussels as well as in Flanders, Wallonia and Portugal, the federal prosecutor's office said.

U.S. Secretary of State Marco Rubio may be walking into unusually unfriendly territory this week when he meets his counterparts from the Group of 7 industrialized democracies — strong American allies stunned by President Donald Trump's actions against them.

Just hours after Trump's steel and aluminum tariffs kicked in — prompting responses from the European Union and Canada and threatening to ignite full-scale trade wars with close U.S. partners — Rubio arrived at the scenic Quebec town of La Malbaie on the St. Lawrence River for two days of talks starting Thursday with the top diplomats of Britain, Canada, France, Germany, Italy and Japan. All of them have been angered by the new American president's policies.

Azerbaijan said Thursday that it had wrapped up peace talks with Armenia aimed to resolve the Caucasus neighbors' decades-long conflict, with the sides agreeing on the text of a possible treaty.

"The negotiation process on the text of the peace agreement with Armenia has been concluded," Azerbaijani Foreign Minister Jeyhun Bayramov told reporters, adding that "Armenia has accepted Azerbaijan's proposals on the two previously unresolved articles of the peace treaty."

An Emirati diplomat earlier identified by Tehran as carrying a letter from U.S. President Donald Trump seeking to jump-start talks over Iran's rapidly advancing nuclear program met Wednesday with Iran's foreign minister in the Iranian capital.

It is unclear how Iran will react to the letter, which Trump revealed during a television interview last week. Its intended recipient, Supreme Leader Ayatollah Ali Khamenei, has said he's not interested in talks with a "bullying government."
