BENGHAZI, Libya — Moammar Gadhafi warned international forces they would "regret" intervening in Libya and his troops attacked the heart of the 5-week-old uprising on Saturday, swarming the first city seized by the rebels with shells, gunfire and warplanes.
"Where is France, where is NATO?" cried a 50-year-old woman in Benghazi. "It's too late."
Leaders from the Arab world, Africa, the United States and other Western powers were holding urgent talks in Paris on Saturday over possible military action after the Libyan government, apparently hoping to outflank the effort, declared a cease-fire.
On Saturday, a warplane was shot down over the outskirts of the key rebel-held city of Benghazi, sending up a massive black cloud of smoke. An Associated Press reporter saw the plane go down in flames and heard the sound of artillery and crackling gunfire in the distance.
Before the plane went down, journalists could hear what appeared to be airstrikes from it. Rebels cheered and celebrated at the crash, though the government denied a plane had gone down -- or that any towns were shelled on Saturday.
The fighting galvanized the people of Benghazi, with young men collecting bottles to make gasoline bombs. Some residents dragged bed frames and metal scraps into the streets to make roadblocks.
At a news conference in the capital, Tripoli, the government spokesman read letters from Gadhafi to President Barack Obama as well as others involved in the international effort.
"Libya is not yours. Libya is for the Libyans. The Security Council resolution is invalid," he said in the letter to French President Nicolas Sarkozy, British Prime Minister David Cameron, and UN Secretary-General Ban Ki-Moon. "You will regret it if you dare to intervene in our country."
To Obama, the Libyan leader was slightly more conciliatory: "If you had found them taking over American cities with armed force, tell me what you would do."
Government spokesman Ibrahim Musa said the rebels are the ones breaking the cease fire by attacking military forces.
"Our armed forces continue to retreat and hide, but the rebels keep shelling us and provoking us," Musa told The Associated Press. ................
