On Saturday, world leaders including US President Donald Trump and Ukrainian President Volodymyr Zelensky will gather in Paris for the reopening of Notre-Dame Cathedral, restored after the 2019 fire. Other attending leaders include German President Frank-Walter Steinmeier and British heir Prince William. Due to adverse weather conditions, the ceremony will be held inside the cathedral instead of its forecourt. US President Joe Biden will be represented by First Lady Jill Biden, as the event will feature a musical program recorded in advance for broadcast.
