In Nagasaki, Japan, prayers and remembrances were held to commemorate the 70th anniversary of the atomic bombing of that city by the US in World War II. Hundreds of Catholics attended a special mass at a rebuilt church that was destroyed in the bombing. Nearly 70,000 died in the 1945 attack. Another atomic bomb that hit Hiroshima just three days earlier killed an estimated 140,000 people. At the Vatican, Pope Francis said the bombings were “a lasting warning to humanity” and renewed calls for an end to war.
