At least 33 people are believed to have lost their lives in bombings in the city of Lviv since 2022. In one attack in September 2024, seven people were killed - including three children - while 50 were injured when Russia struck it with drones and hypersonic missiles in November.

In the past, President Trump also made negative remarks about the Duke and Duchess of Sussex, saying in February he would not get Prince Harry deported if issues with his visa applications raised as the royal "got enough problems with his wife".
