An explosive went off in an apartment building entrance in Monaco, wounding three people, reportedly including a Ukrainian tycoon with ties to Russia. That's according to the exclusive country's chief prosecutor. A search was underway Tuesday for a suspect who fled on foot. Prosecutor Stéphane Thibault said the motive was unclear. Media reports identified Ukrainian construction tycoon Vadym Yermolaiev as being among the injured. Ukrainian news site Ukrainska Pravda said he was targeted by Ukrainian sanctions in 2023 for ties to Russia. A woman and a child were also hurt.

A roof collapse at a tutoring center under construction in Lahore, Pakistan, has killed at least 14 schoolchildren. Police and rescue officials report that the tragedy happened Tuesday. Eight other children are injured and receiving treatment at a hospital. A senior police official says the owner of the tutoring center and another person have been arrested. Rescuers continue to clear the rubble, fearing more children could be trapped. The center was in an aging building, and the roof of its second floor was under construction and collapsed due to poor construction. Building collapses are common in Pakistan due to poorly enforced construction standards.

Older buildings, substandard construction and geography left many neighborhoods in Venezuela vulnerable to collapse in strong earthquakes like the ones that struck the country this week. Engineers and other experts said the back-to-back earthquakes on Wednesday were among the most intense to hit the country in more than a century, leveling buildings and leaving more than 900 dead. Videos and satellite imagery from the disaster zone reviewed by The Associated Press reveal scores of multistory buildings had collapsed.

A new report by the National Park Service says construction of the 250-foot-high triumphal arch that President Donald Trump wants built near the Lincoln Memorial could occur 20 hours per day, year-round, as officials push to complete the project within three years. Tower cranes up to 320 feet tall would be needed to build the arch, which would be more than twice as high as the Lincoln Memorial. The planned site for the arch, across the Potomac River from the memorial, is on a flight path near Ronald Reagan Washington National Airport. The Federal Aviation Administration said Wednesday it is reviewing whether the project’s planned height poses a risk to airplane travel in the area.
