The United Nations Security Council is meeting Tuesday to discuss new sanctions in response to North Korea's latest nuclear test.
The closed-door meetings come as diplomats report the United States and China have reached a tentative deal to punish Pyongyang for last month's test, its third and most powerful yet.
Diplomats told reporters late Monday they hope the council will be able to vote on a resolution by the end of the week. Details of the draft resolution were not immediately available.
The Security Council already unanimously condemned the February 12 nuclear test as a "grave violation" of existing U.N. sanctions on North Korea's nuclear and missile programs. Pyongyang said its test was aimed at its "arch-enemy," the United States.
