WWII bomb: On Wednesday, the Tallboy bomb dropped by Britain’s Royal Air Force in an attack on Germans in 1945 exploded while an attempt to defuse it was taking place. The bomb, weighing in at 5400 kg (2400 kg of which were explosives) was located in the Piast Canal in Poland.

Significance: The explosion forced around 750 local residents to evacuate. The initial plan was to defuse the bomb through deflagration, which is heating the explosive to the point where it burns. Instead, the bomb was detonated and shot water hundreds of feet high. 

Kamala Harris campaign suspension: Senator and vice presidential candidate Kamala Harris’ campaign for presidential nominee Joe Biden was cancelled after a person she had been traveling with and her communications director tested positive for COVID-19. The cancellation of in-person events lasts through Sunday. Harris tested negative for the virus as of thursday.

Significance: With less than a month until the election, and early voting beginning in many states, the last few weeks of campaigning are still very important for both parties. Harris’s campaign activities will resume next Monday, which falls on the same week as the next scheduled presidential debate.
