SEOUL, South Korea (CNN) -- North Korea fired two short-range missiles from its east coast Tuesday -- a day after conducting a nuclear test -- South Korea's Yonhap news agency reported, citing a South Korean official.
North Korean leader Kim Jong-II is suspected to have suffered a stroke last August.
"The North is continuing its saber-rattling," the unnamed official said.
The firings came a day after the reclusive communist state conducted a nuclear test and fired another short-range missile.
U.S. ambassador to the United Nations Susan Rice said Tuesday the international community would not be intimidated by North Korea's "provocative and destabilizing" missile tests.
"If they want to continue to test and provoke the international community, they're going to find that they will pay a price, because the international community is very clear -- this is not acceptable, it won't be tolerated, and they won't be intimidated," Rice told CNN's "American Morning."

The U.N. Security Council -- which includes North Korea's closest ally, China -- on Monday unanimously condemned Pyongyang's nuclear test as a "clear violation" of international law.
After passing the non-binding statement of criticism, the Security Council is now working on passing "a strong resolution with teeth," Rice said. "Those teeth could take various different forms - they are economic levers, they are other levers that we might pursue," she said.
