Britain and France are blaming each other for the deaths of at least 27 people in the English Channel.
It's the worst disaster in the waters since the UN began collecting data in 2014.
The deaths have worsened relations between the UK and France, who're already at odds over Brexit.
France cancelled a weekend meeting with British officials in protest against a letter made public by Prime Minister Boris Johnson.
The UK government had called on France to start taking back all migrants trying to make the crossing.
So, what will it take to stop such a tragedy happening again?
