U.S. President Donald Trump has indicated there was progress with Iran on its nuclear program and hinted that an announcement could come in the "next two days."

Iran on Monday ruled out suspending uranium enrichment as part of any nuclear deal with the United States -- a key demand from Washington in successive rounds of talks between the foes.

North Korea is seeking to arrest those responsible for the failed launch of its second naval destroyer, as it denied the warship suffered major damage — a claim quickly met with outside skepticism.

Harvard University is challenging the Trump administration's decision to bar the Ivy League school from enrolling foreign students, calling it unconstitutional retaliation for defying the White House's political demands.
