US President Donald Trump has urged North Korea to "make a deal" to rein in its nuclear weapons programme.

President Donald Trump said efforts to curb North Korea's nuclear weapons programme would be "front and centre" of his two-day visit to South Korea and he projected optimism that the rising tensions could be calmed.

President Donald Trump will not visit the heavily fortified border between North and South Korea known as the Demilitarised Zone during his upcoming trip to Asia, the White House has said.

A US military passenger and cargo plane crashed today in a populated area south of Seoul, and local reports said the two Americans on board had died.
