Donald Trump has been ridiculed for claiming that he alone can solve the worldwide problem of IsIamic extremism in the wake of the devastating Easter Sunday suicide bombing in Pakistan.

Mr Trump also claimed that he "knew more about Brussels than Brussels knew" and had predicted last week's terror attack in the Belgian capital.

The Republican presidential front-runner's latest comments on foreign policy also included calling President Barack Obama "insane" for wanting to welcome Syrian refugees, and a claim that doing so would lead to the "downfall" of the United States.

On Easter Sunday dozens of people were killed and hundreds injured when a Taliban splinter group targeted a park in Lahore.

Hours later Mr Trump said: "Another radical Islamic attack, this time in Pakistan, targeting Christian women and children. At least 67 dead, 400 injured. I alone can solve."
