**North Korea Denounces UN Action on Sanctions **
The United Nations Security Council has ordered tougher sanctions against North Korea for its December rocket launch, prompting Pyongyang to defiantly hint at another nuclear test.
The 15-member Security Council on Tuesday voted unanimously to condemn the launch as a ballistic missile test banned under existing U.N. sanctions. It also threatened to take "significant action" if Pyongyang conducts more launches or tests.
North Korea responded immediately, saying it would hold no more talks on de-nuclearization. It also vowed to boost its military and "nuclear deterrence," a statement many interpreted as a threat to conduct another nuclear test.
Pyongyang has twice before conducted nuclear tests following U.N. sanctions imposed after long-range rocket launches. Recent satellite photos suggest it may be preparing to conduct a third test.
**African Force for Mali Could Double in Size**
U.N. officials say an African intervention force now deploying in Mali could double from its envisioned 3,300 troops, as more soldiers are needed to help regain control from Islamist militants holding the country's north.
Ivory Coast U.N. Ambassador Bamba, who represents the Economic Community of West African States at the United Nations, says nearly 1,000 troops already are in Mali. He urged the Security Council Tuesday to provide emergency financial and logistical support for the operation.
French and Malian forces have stopped a southward push by the militants, who seized the vast area of northern Mali following a March coup.
A VOA reporter in GAO says most Islamist militants have fled the city since last week, when French warplanes bombed their positions.
