Plane crashes

The head of Poland's ruling conservative party, Jaroslaw Kaczynski, lays down a wreath during a scaled-down observance in memory of his twin brother, the late President Lech Kaczynski, and 95 other prominent Poles who were killed in a plane crash in Russia 10 years ago, at the late president's monument in Warsaw, Poland, on Friday, April 10, 2020. The observances were scaled down to just a few people and no crowd, under social distancing regulations against the spread of the coronavirus. The new coronavirus causes mild or moderate symptoms for most people, but for some, especially older adults and people with existing health problems, it can cause more severe illness or death.(AP Photo/Czarek Sokolowski)
