U.S. President-elect Donald Trump on Tuesday urged the Obama administration to halt prisoner transfers from the Guantanamo Bay military prison in Cuba, calling the detainees "extremely dangerous people."

"There should be no further releases from Gitmo. These are extremely dangerous people and should not be allowed back onto the battlefield," Trump said on Twitter.

U.S. President Barack Obama had vowed to close the prison during his tenure and his administration has signaled it is trying to transfer more detainees before the President leaves office on Jan. 20.

During the presidential election campaign last year, Trump had opposed Obama's plan to shutter the prison, vowing to keep it open and "load it up with some bad dudes."
