The United Stated called on the UN Security Council on Monday to tighten sanctions against North Korea over the secretive state's nuclear activities and artillery attack on South Korea last week.
U.S. ambassador to the UN, Susan Rice, urged the Security Council "to intensify their important ongoing efforts to tighten sanctions enforcement."
The sanctions include a ban on the sale of heavy weapons and nuclear materials to North Korea.
She said the 15-nation board should study information about a nuclear facility 100 km north of Pyongyang which is currently under construction.
She called the North's shelling of the South's Yeonpyeong Island in the Yellow Sea last week "outrageous." The attack killed two marines and two civilians.
"We continue to call on North Korea to cease its irresponsible actions against its neighbors and to fully abide by the terms of the armistice and adhere to its international obligations," Rice said.
