United Nations (CNN) -- Jubilant Libyan rebels in Benghazi erupted with fireworks and gunfire after the U.N. Security Council voted Thursday evening to impose a no-fly zone and permit "all necessary measures" to protect civilians. The opposition, with devoted but largely untrained and under-equipped units, has suffered military setbacks this week. It has said such international action was necessary for it to have any chance of thwarting Moammar Gadhafi's imminent assault on the rebel stronghold. "We're hoping and praying that the United Nations will come up with a very firm and very fast resolution and they will enforce it immediately," said Ahmed El-Gallal, a senior opposition coordinator, before the vote.
