On Monday, BBC News reported figures from the Home Office stating a total of 933 migrants crossed the Channel in small boats in January.
Guardiola said: “The people who have to do that, run away from their countries, go in the sea and then go on a boat to get rescued – don’t ask if he is right or wrong, rescue him. It is about a human being.
“After we can agree, criticise but everyone is right, everyone has an idea and you have to express it. People are dying, you have to help him. Protecting the human being and human life is the only thing we have.”
Last month, two US citizens were shot dead by federal agents carrying out US President Donald Trump’s immigration crackdown in Minneapolis over the past month.
Fan group Football Supporters Europe (FSE) says it is “extremely concerned by the ongoing militarisation of police forces in the US” before this summer’s World Cup in North America.
Guardiola added: “When I see the images, I am sorry it hurts. That is why in every position I can help speak up to be a better society, I will try and will be there. All the time. It is for my kids, my families, for you.
“From my point of view, the justice? You have to talk. Otherwise it will just move on. Look what happened in the United States of America, Renee Good and Alex Pretti have been killed. Tell me how you can defend that?
“There is not a perfect society, nowhere is perfect, I am not perfect, we have to work to be better.”
