At least 36 people were killed in a train collision Tuesday night in Tempi, central Greece, the Greek Fire Service said. A passenger train was carrying more than 350 people when it collided with a freight train. The two trains involved in the collision were traveling on the same track for many kilometers before the incident occurred, state-owned public broadcaster ERT reported. The passenger train had changed lanes and switched to a cargo track before the collision, according to ERT. The passenger train had been traveling from the capital Athens to Thessaloniki, Greece’s second-largest city, following a nationwide carnival that took place over the weekend.

Scientists say tests in East Palestine, Ohio, show unusually high levels of some chemicals in the aftermath of a toxic train wreck last month. Nine of the dozens of chemicals that the EPA has been monitoring are higher than would normally be found in the area, according to a group of scientists from Texas A&M and Carnegie Mellon University. The highest levels found in the area were of a toxic chemical called acrolein, the analysis says. Acrolein is used to control plants, algae, rodents and microorganisms. It can cause inflammation and irritation of the skin, respiratory tract and mucous membranes, according to the CDC. In response to angry residents, the EPA said it will continue to monitor the air quality in the area and in people’s homes.

Chicago Mayor Lori Lightfoot lost her reelection bid Tuesday, marking the first time in more than 30 years that Chicago has ditched its mayor. Lightfoot, the first Black woman and first out gay person to serve as the city’s mayor, failed to make a top-two runoff amid growing concerns about rising crime in Chicago. Paul Vallas, a longtime public schools chief who ran on a tough-on-crime message, and Brandon Johnson, a Cook County commissioner backed by progressives and the Chicago Teachers Union, will advance to the April runoff, CNN projects. More than 507,000 ballots had been cast by the time polls closed Tuesday, Chicago elections officials said. More mail-in votes will be added to that total as they arrive.

Vaccine advisers to the FDA narrowly voted Tuesday in favor of Pfizer’s RSV vaccine for adults over the age of 60, paving the way for approval of the nation’s first RSV vaccine, despite some safety concerns. The committee members voted 7-4, with one abstention, that there are adequate data to support the safety and effectiveness of the vaccine for the prevention of a lower respiratory tract disease caused by the respiratory syncytial virus, or RSV, among older adults. The FDA, which typically follows the independent committee’s recommendations, is scheduled to decide on approval by May, ahead of RSV’s typical winter surge. RSV is a highly contagious virus responsible for an estimated 177,000 hospitalizations and 14,000 deaths per year among adults 65 or older, according to the CDC. 

Russian officials today accused Ukraine of launching a spate of attempted drone strikes targeting infrastructure deep inside Russia, including near its capital. Following the alleged attacks, Russia’s second-largest city of St. Petersburg closed its airspace and briefly banned incoming flights on Tuesday, according to state media. Meanwhile, Finland has begun construction of barrier fences on its eastern border with Russia. The Finnish border was one of the few entry points for Russians after many Western countries shut their air space and borders to Russian planes in response to the Ukraine invasion. Helsinki later closed its border at the end of last September when Russians tried to flee President Vladimir Putin’s “partial mobilization” of hundreds of thousands of citizens to fight in the war.
