Nuclear-armed Pakistan is a vital problem. I can solve radical Islamic terrorism, says Donald Trump

A nuclear-armed Pakistan is a "very very vital problem," Republican presidential frontrunner Donald Trump has said, asserting that the country needs to "get a hold of" its situation.

During a townhall meeting in Wisconsin - where the Republican presidential primary is scheduled to be held on 5 April - Trump told CNN:

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

"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."

"I'm talking about radical Islamic terrorism. I will solve it far better than anybody else running."

A large crowd - including a number of Christian families - were present at the crowded Gulshan-e-Iqbal Park of Allama Iqbal Town in Lahore when a powerful blast took place on 27 March. The Jamaatul Ahrar, a splinter group of the Tehrik-i-Taliban Pakistan (TTP), has claimed responsibility for the brutal attack - which was carried out by a suicide bomber, believed to be in his 20s.
