Pyongyang, North Korea (CNN) -- The U.N. Security Council met Friday to discuss North Korea's botched long-range missile launch, an act U.N. officials called deplorable and destabilizing despite its failure.

Amid concerns that North Korea will try to recover from the embarrassing failure with a nuclear test or military move, a spokesman for U.N. Secretary-General Ban Ki-moon warned the secretive country's regime not to "undertake further provocative actions that will heighten tension in the region."

The missile broke apart shortly after launch Friday morning, then fell into the ocean.

The launch drew condemnation from United States and countries in the region, as well as an unusual admission of failure from Pyongyang. The normally secretive regime has previously insisted that failed launches had actually been successful.

"Scientists, technicians and experts are now looking into the cause of the failure," North Korea's official Korean Central News Agency said in a report, which was also read out in a news broadcast on state-run television.

North Korea said the missile was designed to carry an observation satellite into orbit. But the United States, South Korea and Japan said that was a cover for a long-range ballistic missile test.

"They have to understand they only deepened their isolation by going down this road," Ben Rhodes, U.S. deputy national security adviser for strategic communications, said Friday.

More provocative action could lead to tighter sanctions and the Security Council will begin deliberations Friday on "how to deliver a message" to North Korea over the launch, Rhodes said.

In the meantime, the United States has suspended plans to provide food aid to North Korea as a result of the launch, Rhodes said.

"Their efforts to launch a missile clearly demonstrates that they could not be trusted to keep their commitment therefore we are not going forward with an agreement to provide them with any assistance," he said.

"We have not provided them with any assistance and it is impossible to see how we could move forward with the February agreement given the action that they have taken."

North Korea had made much of the launch, which coincided with celebrations surrounding the 100th anniversary of the birth of its late founding leader, Kim Il-sung.

The regime had invited journalists and space experts from around the world to view the launch pad and the purported satellite, and called the effort "an inspiring deed and an event of historic significance."

A recent South Korean intelligence report noted that the two previous failed rocket launches that Pyongyang said were intended to put satellites into orbit were followed a few weeks or months later by nuclear tests.

"Often when they've had failures of this kind, they reach into their bag and find other things to do," said Christopher Hill, a former lead U.S. negotiator at talks over the North Korean nuclear program who now teaches at the University of Denver. "And so I would be concerned about the potential of an actual nuclear test coming up."

The rocket took off at 7:38 a.m. on Friday. It broke into two parts after about two minutes, according to the South Korean Defense Ministry.

About six minutes later, the two sections of the rocket separated into smaller pieces, which dropped into the sea, the ministry said.

The North American Aerospace Defense Command and U.S. Northern Command officials also tracked the missile.

"Initial indications are that the first stage of the missile fell into the sea 165 km west of Seoul, South Korea," they said in a news release. "The remaining stages were assessed to have failed and no debris fell on land. At no time were the missile or the resultant debris a threat."

The debris is spread over an area about 20 kilometers (12 miles) long, said Kim Kwan-jin, the South Korean defense minister.

South Korea, which has criticized the launch as a "grave provocation," said it was searching the waters near where the rocket fell for debris -- a chance to gain insights into the North's technology.

The South Korean military was "fortifying its stance," said a spokesman for the South Korean Defense Ministry.

The White House press secretary, in a statement, said that North Korea's failed launch "threatens regional security, violates international law and contravenes its own recent commitments."

Noriyuki Shikata, a spokesman for Japanese Prime Minister Yoshihiko Noda, said the international ramifications could be significant. "This is something that we think is a regrettable development," he said.

"Our government strongly criticizes their action," said South Korean Minister of Foreign Affairs Kim Sung-hwan. "They have ignored the starvation of their people and spent money on missiles. It is very unfortunate."

Vitaly Churkin, Russia's U.N. ambassador, said before the launch that Security Council members didn't have a "clear agreement" about what steps to take if the launch were to go ahead. "But one thing I can tell you: We have unanimity of understanding that if it were to happen, that would be a clear violation of two Security Council resolutions."

Following the rocket's failure, China, the closest ally of North Korea, urged the parties involved to "remain calm and exercise restraint, and not do anything that would harm the peace and stability of the peninsula," according to a statement posted on the website of the Ministry of Foreign Affairs.

The launch Friday came amid North Korean preparations to mark the 100th anniversary of the birth of Kim Il Sung, the founder of North Korea who ruled the Communist state for more than four decades. His birthday on April 15, known as the "Day of the Sun," is a key public holiday.

On Wednesday, North Korea's ruling Workers' Party held a special conference that helped firm up the position of Kim's grandson, Kim Jong Un, the secretive state's new leader.

Korean television showed a somber Kim standing beneath two towering statues of his grandfather and his late father, Kim Jong Il, while receiving applause from party functionaries and the military. Kim Jong Il was given the title of "eternal general secretary" of the Workers' Party, while Kim Jong Un was named the party's first secretary.

The last time Pyongyang carried out what it described as a satellite launch, in April 2009, the U.N. Security Council condemned the action and demanded that it not be repeated.

That rocket traveled 2,300 miles before its third stage fell into the Pacific Ocean. And in 2006, a missile failed after about 40 seconds in flight.
