UN Security Council tightens screws on Pyongyang with new sanctions

The UN Security Council on Wednesday slapped a series of fresh sanctions on North Korea following the large-scale nuclear test that Pyongyang conducted in September. The sanctions including the slashing of the North's annual export revenue by 25 percent were approved by all 15 members of the council. North Korea's coal exports are now capped by 60 percent and its overseas shipments of copper, nickel, silver and zinc are banned.
