Weighing withdrawal from the Iran nuclear deal, President Donald Trump declared on Tuesday that if the Iranians "restart their nuclear program, they will have bigger problems than they've ever had before." Trump issued his warning alongside French President Emmanuel Macron in the Oval Office, where the two allies were to discuss the multinational nuclear accord, the war in Syria and other issues during a day of meetings at the White House. The pair discussed the possibility of a new deal, one Trump said would have "with solid foundations." Trump also informed Macron and his TV audience that North Korean leader Kim Jong Un wanted to meet "as soon as possible." The president, who once derided Kim as "Little Rocket Man," said the North Korean dictator had been "very open" and "very honorable" so far. Get More

Authorities said Monday that three Mexican film students who went missing in March in Guadalajara were kidnapped, tortured and killed, and their bodies were dissolved in acid, NBC News reported. Javier Salomón Aceves Gastélum, Daniel Díaz, and Marco Ávalo were last seen on March 19 in the municipality of Tonala, in the state of Jalisco, filming a class project during their Spring Break. The three aspiring filmmakers were students at the Universidad de Medios Audiovisuales. According to state prosecutors, their car broke down during the trip and they were later kidnapped by gunmen from the Jalisco New Generation Cartel (CJNG), who confused them for members of a rival gang. Academy Award winning director Guillermo del Toro, who is a native of Guadalajara, expressed outrage on social media in response to the killings.

Southwest Airlines runs its planes hard. They make many short hops and more trips per day than other U.S. airliners, which adds to wear and tear on parts, including the engines. As the investigation into last week's deadly engine failure continues, Southwest CEO Gary Kelly could face questions about whether the company's low-cost business model — which puts its planes through frequent takeoffs and landings — is putting passengers at risk. Some aviation safety experts said they see no reason for alarm. And, in fact, Southwest's safety record is enviable: Until last week, no passenger had died in an accident during its 47-year history.
