UNITED NATIONS — The United Nations Security Council voted Thursday to authorize military action, including airstrikes against Libyan tanks and heavy artillery and a no-fly zone, a risky foreign intervention aimed at averting a bloody rout of rebels by forces loyal to Col. Muammar el-Qaddafi.
Diplomats said the resolution — which passed with 10 votes, including the United States, and abstentions from Russia, China, Germany, Brazil and India — was written in sweeping terms to allow for a wide range of actions, including strikes on air-defense systems and missile attacks from ships. Military activity could get under way within a matter of hours, they said.
Benghazi erupted in celebration at news of the resolution’s passage. “We are embracing each other,” said Imam Bugaighis, spokeswoman for the rebel council in Benghazi. “The people are euphoric. Although a bit late, the international society did not let us down.”
The vote, which came after rising calls for help from the Arab world and anguished debate in Washington, left unanswered many critical questions about who would take charge, what role the United States would play and whether there was still enough time to stop Colonel Qaddafi from recapturing Benghazi and crushing a rebellion that had once seemed likely to drive him from power. After the vote, President Obama met with the National Security Council to discuss the possible options, European officials said. He also spoke by telephone on Thursday evening with Prime Minister David Cameron of Britain and President Nicolas Sarkozy of France, the White House said.
Speaking on a radio call-in show in Tripoli before the vote, Colonel Qaddafi raised the level of urgency on the vote, saying that his forces would begin an assault on Benghazi that night.
“We will come house by house, room by room. It’s over. The issue has been decided,” he said, offering amnesty to those who laid down their arms. To those who continued to resist, he vowed: “We will find you in your closets. We will have no mercy and no pity.”
After the Security Council’s vote, Libya’s deputy foreign minister, Khalid Kaim, said at a news conference in Tripoli early on Friday morning that the Qaddafi government welcomed the resolution’s calls for the protection of civilians, which he insisted his government had always sought. But he warned against foreign countries’ trying to arm the rebels. “That means they are inviting Libyans to kill each other,” he said.
Mr. Kaim said the Qaddafi government was ready for a cease-fire with the rebels, “but we need to talk to someone to agree on the technicalities of the decision.” And he declined to address the possibility that the government’s forces were continuing to push swiftly toward Benghazi.
James M. Lindsay, the director of studies at the Council on Foreign Relations, said of the Security Council’s decision: “It’s going to be tougher to stop Qaddafi today than it was a week ago. The issue is not going to be settled in the skies above Benghazi, but by taking out tanks, artillery positions and multiple-launch rocket systems on the ground.”
Mr. Lindsay said that would require helicopter gunships and other close-in support aircraft rather than advanced fighter planes. Other analysts said repelling Colonel Qaddafi’s forces might require ground troops, an option that has been ruled out by senior American officials.
A Pentagon official said Thursday that decisions were still being made about what kind of military action, if any, the United States might take with the allies against Libya. The official said that contingency planning continued across a full range of operations, including a no-fly zone, but that it was unclear how much the United States would become involved beyond providing support.
That support is likely to consist of much of what the United States already has in the region — Awacs radar planes to help with air traffic control should there be airstrikes, other surveillance aircraft and about 400 Marines aboard two amphibious assault ships in the region, the Kearsarge and the Ponce.
The Americans could also provide signal-jamming aircraft in international airspace to muddle Libyan government communications with its military units.
A European diplomat said that Britain and France were still waiting to hear what role the United States would take in any military action in Libya. “One decision that needs to be made,” he said, “is whether there will be a command and control operations in Britain or in France.”
Beyond that, the diplomat said that officials in Britain, France and the United States were all adamant that Arab League forces take part in the military actions and help pay for the operations, and that it not be led by NATO, to avoid the appearance that the West was attacking another Muslim country.
The United States has played a complicated role in the debate over military involvement, initially expressing great reluctance about being drawn into another armed conflict in a Muslim country but subsequently unnerved by the reports of Colonel Qaddafi’s gains.
But diplomats said the moral imperative of protecting civilians from Colonel Qaddafi and the political imperative of United States not watching from the sidelines while a notorious dictator violently crushed a democratic rebellion had helped wipe away lingering doubts.

Member states voted to approve a resolution that will impose a no-fly zone over Libya during a meeting of the Security Council. Russia abstained.
She went on to say Qaddafi would do “terrible things” to Libya and its neighbors. “It’s just in his nature. There are some creatures that are like that.” Her remarks, applauded by the studio audience where she appeared, amounted to the administration’s most stridently personal attacks on the Libyan leader, echoing President Ronald Reagan’s “mad dog of the Middle East.”
The resolution — sponsored by Lebanon, another Arab state, and strongly backed by France, Britain and the United States — explicitly mentions the need to protect civilians in the rebel stronghold Benghazi, “while excluding an occupation force.” It calls to “establish a ban on all flights in the airspace” and an immediate cease-fire.
Mrs. Clinton said Thursday that establishing a no-fly zone over Libya would require bombing targets inside the country to protect planes and pilots. She said other options being considered included the use of drones and arming rebel forces, though not ground troops, an option that appeared to be ruled out Thursday by the State Department’s highest-ranking career diplomat, Under Secretary William J. Burns.
The vote was also a seminal moment for the 192-member United Nations and was being watched closely as a critical test of its ability to take collective action to prevent atrocities against civilians. Diplomats said the specter of former conflicts in Bosnia, Rwanda and Darfur, when a divided and sluggish Security Council was seen to have cost lives, had given a sense of moral urgency to Thursday’s debate. Yet some critics also noted that a no-fly zone authorized in the early 1990s in Bosnia had failed to prevent some of the worst massacres there, including the Srebrenica massacre.
The resolution stresses the necessity of notifying the Arab League of military action and specifically notes an “important role” for Arab nations in enforcing the no-fly zone. Diplomats said Qatar and the United Arab Emirates were considering taking a leading role, with Jordan, Saudi Arabia and Egypt also considering participating.
The participation of Arab countries in enforcing a no-fly zone has been seen as a prerequisite for the United States, keen not to spur a regional backlash. Diplomats said debate on the resolution had been contentious, with Russia and China reluctant to support military intervention. The German foreign minister, Guido Westerwelle, also opposed military action and called for tougher sanctions.
Security Council members said they were aware that military units loyal to Colonel Qaddafi were surrounding the strategically located town of Ajdabiya and massing for a push up the road to the rebel stronghold of Benghazi, 100 miles away.
