New York, Dhu-AlHijjah 13, 1438, Sep 4, 2017, SPA -- The U.N. Security Council is holding its second emergency meeting in a week about North Korea on Monday after a powerful nuclear test explosion added another layer of urgency for diplomats wrestling with what to do about the North's persistent weapons programs. Scheduled after North Korea said it detonated a hydrogen bomb underground Sunday, the emergency session comes six days after the council strongly condemned Pyongyang's "outrageous" launch of a ballistic missile over Japan. Less than a month ago, the council imposed its stiffest sanctions so far on the reclusive nation, AP reported. North Korea is "deliberately undermining regional peace and stability," the council said Tuesday when it rebuked the missile test, reiterating demands for the country to halt its ballistic missile and nuclear weapons programs. Requested by the United States, Japan, France, Britain and South Korea, the Security Council meeting Monday could bring additional condemnation and discussion of other potential steps. British Prime Minister Theresa May called in a statement Sunday for speeding the implementation of existing sanctions and "looking urgently" at new measures in the council. --SPA 14:43 LOCAL TIME 11:43 GMT www.spa.gov.sa/w481318
