Russia on Monday claimed its deadly missile attack on Ukraine's Sumy that killed and wounded scores including children had targeted a gathering of Ukrainian troops, while European leaders condemned the attack as a war crime.

Ukrainian officials have said two ballistic missiles on Palm Sunday morning hit the heart of Sumy, a city about 30 kilometers (less than 20 miles) from Ukraine's border with Russia, killing at least 34, including two children, and wounding 119. It was the second large-scale attack to claim civilian lives in Ukraine in just over a week.

The Kremlin on Monday hailed last week's talks on the Ukraine conflict between President Vladimir Putin and Donald Trump's envoy Steve Witkoff.

"Such contacts are extremely useful and very effective," Kremlin spokesman Dmitry Peskov said, adding the talks in Saint Petersburg presented a "needed channel" through which Putin and Trump could pass information to each other.

French Interior Minister Bruno Retailleau was on a visit to Rabat on Monday, where he is expected to discuss security cooperation with his Moroccan counterpart Abdelouafi Laftit.

Talks will primarily focus on migration cooperation, the fight against organized crime and drug trafficking, according to the French interior ministry.

The head of the UN nuclear watchdog, Rafael Grossi, will arrive in Tehran on Wednesday for discussions with senior Iranian officials, state media reported, ahead of new round of talks between Iran and the United States.

During his visit, Grossi is set to meet Iranian Foreign Minister Abbas Araghchi and Mohammad Eslami, head of the Atomic Energy Organization of Iran (AEOI), the state news agency IRNA reported on Monday, citing Deputy Foreign Minister Kazem Gharibabadi.

President Donald Trump bitterly attacked "60 Minutes" shortly after the CBS newsmagazine broadcast stories on Ukraine and Greenland on Sunday, saying the network was out of control and should "pay a big price" for going after him.

"Almost every week, 60 Minutes ... mentions the name 'TRUMP' in a derogatory and defamatory way, but this Weekend's 'BROADCAST' tops them all," the president said on his Truth Social platform. He called on Federal Communications Commission Chairman Brendan Carr to impose maximum fines and punishment "for their unlawful and illegal behavior."

Russian missiles struck the heart of the Ukrainian city of Sumy as people gathered to celebrate Palm Sunday, killing at least 34 people, officials said, in the second large-scale attack to claim civilian lives in just over a week.

The two ballistic missiles hit around 10:15 a.m., officials said. Images from the scene showed lines of black body bags on the side of the road, while more bodies were seen wrapped in foil blankets among the debris. Video footage also showed fire crews fighting to extinguish the shells of burned-out cars among the rubble from damaged buildings.

Russian Foreign Minister Sergei Lavrov will meet his Iranian counterpart Abbas Araghchi in Moscow, Russian state agencies said Monday, citing the foreign ministry.

"We are expecting Iranian colleagues, talks with Sergei Lavrov as well as meetings with Russian officials are planned," Russian foreign ministry spokeswoman Maria Zakharova said, after Iran announced that its top diplomat was heading to Moscow later in the week.

The United States wants a nuclear agreement "as soon as possible", Iran said after rare talks on Saturday, as U.S. President Donald Trump threatens military action if they fail to reach a deal.

The long-term adversaries, who have not had diplomatic relations for more than 40 years, are seeking a new nuclear deal after Trump pulled out of an earlier agreement during his first term in 2018.

U.S.-Iran talks on Saturday in Oman marked a "step forward" between the two adversaries, the White House said, describing discussions including President Donald Trump's regional envoy as "positive and constructive."

Iranian Foreign Minister Abbas Araghchi said Saturday his country seeks a "fair and honorable" deal with the United States, hours before the start of talks between the two sides.
