Mexico’s president says migrants set fire to mattresses in an immigration detention center where 39 died in protest after learning they would be deported. A fire in a dormitory at a center near the U.S. border was one of the deadliest incidents ever at an immigration lockup in the country. Hours after the fire broke out late Monday, rows of bodies were laid out under shimmery silver sheets outside the facility in Ciudad Juarez, which is across from El Paso, Texas, and a major crossing point for migrants. Ambulances, firefighters and vans from the morgue swarmed the scene.

Protests and strikes against unpopular pension reforms are again gripping France. Many thousands of demonstrators are marching Tuesday and the Eiffel Tower is closed. Police have ramped up security amid government warnings that radical demonstrators intended “to destroy, to injure and to kill.” In Paris, striking workers waving burning flares invaded and blocked train tracks serving one of the French capital's main railway stations. Fears that violence could mar the demonstrations prompted what Interior Minister Gérald Darmanin described as an unprecedented deployment of 13,000 officers. It's the latest round of nationwide demonstrations and strikes against unpopular pension reforms and President Emmanuel Macron’s push to raise France’s legal retirement age from 62 to 64.

Ukraine’s president has visited the Sumy region in northern Ukraine, continuing his tour over recent days of areas of the country that have felt the brunt of Russia’s full-scale invasion. President Volodymyr Zelenskyy met Tuesday with officials and local people in two cities in the region that borders Russia. It was partially occupied by Russian forces after the full-scale invasion last year. The Russians withdrew from the region by early April. Zelenskyy’s trip followed his visits over the past seven days to the eastern Kherson and Kharkiv regions which were retaken last year from the Kremlin’s forces, to the intensely contested Donetsk area of Bakhmut, and to Zaporizhzhia in the south.

Officials say a Russian court has convicted a single father over social media posts criticizing the war in Ukraine and sentenced him to two years in prison. His lawyer and activists say the case was brought to the attention of authorities by his daughter’s antiwar drawings at school. The case of Alexei Moskalyov in the town of Yefremov, south of Moscow, has drawn international attention. It's a grim indication the Kremlin is intensifying its crackdown on dissent, targeting more people and handing out harsher punishments for any expression of criticism of the war. In a twist to the case, court officials say the 54-year-old Moskalyov fled house arrest overnight and wasn’t present for the trial's outcome.
