Remembered

Londoners and foreigners crowded into Trafalgar Square with flowers and candles on March 23 to commemorate those killed a day earlier in a terror attack near the heart of the British capital. Four people died and nearly 30 were injured when 52-year-old Khalid Masood plowed a rented SUV into civilians on Westminster Bridge and then fatally stabbed a police officer outside Parliament. British-born Masood, a Muslim who investigators said had showed interest in jihad, was killed by police during the attack. At the vigil, several thousand people held a moment of silence for victims. “Londoners will never be cowed by terrorism,” Mayor Sadiq Khan told the crowd.

Murdered

Denis Voronenkov, a former Russian politician who openly criticized President Vladimir Putin’s government, was shot to death outside a hotel in Kiev, Ukraine, on March 23. Voronenkov, 45, had served in the Russian parliament and helped to pass an anti-free speech bill, but later seemed to change his political views. He fled Russia to Ukraine last October with his wife. Last month he told Radio Free Europe his country had “gone crazy” and called Russia’s annexation of Crimea “illegal.” Ukrainian President Petro Poroshenko described Voronenkov’s killing as “state terrorism,” noting it had the hallmarks of the Russian secret police. Russia denied involvement in the murder. Voronenkov’s assassin died after being shot by a bodyguard.

Launched

North Korea launched yet another missile on March 22, but it exploded within seconds of taking off. The failed launch came at a time of heightened tensions over North Korean dictator Kim Jong Un’s missile tests: The country conducted at least three rocket engine tests in March, and on March 6 fired four ballistic missiles into the Sea of Japan. The Trump administration has proposed stricter financial sanctions on Pyongyang in response. A North Korean official said sanctions would not deter the country’s nuclear and missile programs.

Died

David Rockefeller, famed philanthropist and banker, died March 20 at the age of 101. He was the last surviving grandson of American oil magnate John D. Rockefeller. David Rockefeller earned a doctorate during the Great Depression, served active duty as an officer during World War II, and launched a banking career in 1946, rising swiftly to become the president of Chase Manhattan. As sole chief executive, he courted heads of state around the world, expanding his bank’s international influence, and in the 1970s steered Chase Manhattan through a recession and a financial scandal. Rockefeller continued to work into his 90s but was also known for donating hundreds of millions of dollars to art, education, and museums.
