CALGARY - A San Francisco-based environmental group has launched a billboard campaign in several U.S. cities asking Americans to rethink their travel plans to Alberta because of the oilsands.

Corporate Ethics International has set up up the ads in Denver, Portland, Seattle and Minneapolis "revealing Alberta to be one of the world's dirtiest destinations." The campaign is targeting U.S. cities with the most Canadian travel.

At least 10 million HIV-AIDS deaths could be averted by 2025, but doing so requires a dramatic expansion and simplification of treatment, the man leading the international fight against the epidemic says.

A cap was back in place on BP's broken oil well in the Gulf of Mexico after a deep-sea blunder forced crews to temporarily remove what has been the most effective method so far for containing some of the massive spill.

Engineers using remote-controlled submarines repositioned the cap late Wednesday after it had been off for much of the day. It had captured 700,000 gallons of oil in the 24 hours before one of the robots bumped into it.

MONTCLAIR, Calif. - Prince Sagala desperately searched for her son and daughter for 15 years, fearing she had lost them forever to the estranged husband who took them to his native Mexico.

Her fears were replaced by joy when she typed her daughter's name into Facebook on a library computer and discovered that her children, now 16 and 17, were safe and with their father. She soon learned they were living near Disney World in Florida.

Pensacola, Florida (CNN) -- About 250,000 gallons of oil have been funneled from a ruptured well in the Gulf of Mexico, BP says. That's less than a third of the 798,000 gallons of crude federal authorities estimate are gushing into the ocean every day. After many failed attempts, BP was able to place the cap on the well this week and begin siphoning oil onto the drill ship Discover Enterprise.

Engineers hope to funnel more oil but must be careful about the pressure within the cap, said Coast Guard Adm. Thad Allen, the federal government's response manager. Once the pressure is eased, BP plans to shut down valves in the cap, which are allowing oil to escape, Allen said Saturday. Company officials said they hope closing the vents will greatly reduce the amount of oozing crude. The operation is capable of capturing 630,000 gallons a day.
