Republican presidential front-runner Donald Trump has said that nuclear-armed Pakistan is a "very, very vital problem", and even asserted that Pakistan has to "get a hold of" its situation.

Trump told CNN that, "Pakistan is a very, very vital problem and really vital country for us because they have a thing called nuclear weapons. They have to get a hold of their situation."

Referring to the terrorist attack in Lahore that happened on Easter, claiming 74 lives and injuring 300 others, he said, "When I see that and when I see it put in a park because it was mostly Christians, although many others were killed other than Christians, I think it's just absolutely a horrible story."
