DUBAI, United Arab Emirates — Dubai got a $10 billion lifeline from oil-rich Abu Dhabi to save one of its prized companies from imminent default today, calming fears for now about the city-state's shaky finances. Dubai's main stock market spiked more than 10 percent on the news.

Dubai World — a sprawling conglomerate with assets ranging from the ocean-liner Queen Elizabeth 2 to luxury retailer Barney's New York — had been up against a deadline to repay a pile of loans from its Nakheel property division. Some $4.1 billion of the emergency funds will be used to pay off those bills. The rest will go to shore up Dubai World itself.

Dubai officials' reluctance to fully stand behind Dubai World's $60 billion in debts had raised serious concerns about the emirate's creditworthiness, and the move by Abu Dhabi appeared aimed at quashing those worries before they undercut confidence in the United Arab Emirates as a whole. The two emirates share control of the UAE, a federation of seven semiautonomous city-states.

The bailout is the latest by Abu Dhabi. The emirate which controls the UAE's presidency has directly and indirectly provided Dubai with $25 billion over the past year, mostly by buying Dubai bonds.

ROME — Premier Silvio Berlusconi is in pain and will remain hospitalized until at least Tuesday with a fractured nose and two broken teeth from an attack by a mentally disturbed man who hit him in the face with a statuette, doctors and aides said.A government official said he expected the premier's protection to be tightened after an emergency meeting of security officials.Berlusconi was rushed to the San Raffaele hospital in Milan with his face covered in blood after the attack in the northern Italian city Sunday afternoon.Police first said it appeared the assailant had punched Berlusconi in the face while clutching a souvenir statue of Milan's Duomo, or gargoyled cathedral, which symbolizes the city. But state TV later showed a video, somewhat blurry, of what appeared to be the attacker's hand coming close to Berlusconi's face while holding the statue, then letting go of the object at the last minute as it hit the premier's face.The attacker, a 42-year-old man with a history of psychological problems, was arrested.
