NUCLEAR terrorism is the gravest threat to the global security, US President Barack Obama will warn today as he calls for action to keep nuclear-grade material out of the hands of extremists.
At a two-day summit, the biggest gathering of world leaders led by an American president since the end of World War Two, Mr Obama will seek international co-operation on securing every ounce of loose nuclear material within four years.
"It is absolutely fundamental to view this summit with the starting point," said Ben Rhodes, a deputy US national security adviser.
"We know that terrorist groups, including al-Qa'ida, are pursuing the materials to build a nuclear weapon, and we know that they have the intent to use one."
Meanwhile Hillary Clinton, the US Secretary of State, warned that a 10-kiloton nuclear bomb -- smaller than the device dropped on Hiroshima in 1945 -- detonated in Manhattan's Times Square could kill a million people.
