Trump calls for speedy trial of Afghan bomber

"We must have speedy, but fair trials, and we must deliver a just and very harsh punishment to these people," Trump told his supporters at an election rally in Florida yesterday.

He thanked the police for arresting Ahmad Khan Rahami, the man suspected in bombings in New York and New Jersey.

"Today, we have caught this evil thug who planted the bombs. Thank you, law enforcement. Thank you, police. But the bad part is now we will give him amazing hospitalisation," Trump, 70, said.

"He will be taken care of by some of the best doctors in the world. He will be given a fully modern and updated hospital room. And he will probably even have room service, knowing the way our country is," he said.

"And on top of all of that, he will be represented by an outstanding lawyer. His case will go through the various court systems for years, and in the end, people will forget and his punishment will not be what it once would have been. What a sad situation," he rued.

Trump said the US must use whatever lawful methods are available to obtain information from the apprehended suspect to get information before it is no longer timely.

"The Congress should pass measures to ensure that foreign enemy combatants are treated as such. These are enemies. These are combatants. And we have to be tough and we have to be strong," he said.

Rahami will be questioned in connection with the explosion that occurred on Sunday in Chelsea district of Manhattan, New York, and injured 29 people
