The United Stations Security Council on Friday imposed tough new sanctions on North Korea for its recent nuclear test.

The resolution concludes a tighter arms embargo and additional financial restrictions, and allows inspections of suspect cargo in ports and on the high seas.

By unanimously adopting resolution 1874, the 15-member body condemned the 25 May nuclear test conducted in 'violation and flagrant disregard' of relevant Council resolutions, particularly 1695 and 1718, said the U.N. in a statement.

U.S. deputy ambassador Rosemary DiCarlo said that Friday's vote was a strong and united international response to North Korea's unacceptable behavior.

The U.N. also demanded that North Korea refrain from further nuclear tests or launching ballistic missiles.
