Indian Wells, California  - Roger Federer suffered a fourth straight humiliation at the hands of Andy Murray on Saturday with the Scot running away with the third set to reach the final of the Indian Wells Masters 6-3, 4-6, 6-1.

Federer has not beaten world number 3 Murray since the US Open final six months ago. In the interim, the Scot has won showdowns at Madrid, Shanghai, Doha and now in the Californian desert.

Murray will await the winner from 2007 champion Rafael Nadal and American Andy Roddick, who leads the ATP with victories this season on 23.

Washington  - At least 5,000 residents were evacuated in eastern Pennsylvania after a truck carrying 33,000 pounds of toxic hydrofluoric acid overturned early Saturday.

Driver Raymond Leblanc, 54, of Ontario, Canada, lost control of the vehicle while trying to avoid hitting a deer. He was initially trapped in the truck, but was rescued unhurt. Another passenger was also removed from the site and no other injuries were reported, police said.

Most of the acid was in the form of pressurized gas, police told broadcaster CNN and the leak was plugged eight and a half hours after the trailer overturned near Wind Gap, Pennsylvania.

Washington  - US President Barack Obama on Saturday welcomed France's decision to return to NATO's military command after a 43- year absence, saying France's "full participation ... will contribute to a stronger alliance and a stronger Europe."

"I enthusiastically welcome the decision made by French President Nicolas Sarkozy to fully reintegrate France into the NATO alliance," Obama said in a statement.

Tehran  - Iran's Supreme Leader Ayatollah Ali Khamenei on Saturday rejected an offer by US President Barack Obama to open a new era in relations until Tehran could see real changes in US policies.

"The Iranian nation can neither be tricked [by the messages] nor threatened. The changes claimed by the US should be real and not just in rhetoric," Khamenei said.

San Francisco  - On March 24, 1989, a massive tanker captained by a man who had allegedly been drinking, sailed outside regular Alaskan shipping lanes and hit a reef, causing one of the worst environmental disasters in US history.

The Exxon Valdez, at the time one of the most advanced tankers in the world, split, spilling approximately 40 million litres of crude oil into the delicate and pristine Arctic environment of the remote Prince William Sound.

Washington  - At a time when few have money to spare, the cost of running a computer is not an insignificant concern.

A typical desktop computer, together with a monitor and printer, can consume as much electricity as five or six powerful incandescent household light bulbs.

If left running for long periods of time - or even 24 hours a day - a computer can easily cost you more in electrical bills than its original purchase price.
