BERKELEY, Calif. — The families of three Americans being held in Iran plan to release video footage that they say proves the three were simply on vacation and had no underhand intentions when they strayed across the border.

Shane Bauer, 27, Sarah Shourd, 31, and Josh Fattal, 27, have been detained since July 31. They apparently crossed into Iran by accident while hiking in a scenic area in northern Iraq. They have been visited by Swiss diplomats, who oversee U.S. interests in Iran, but have had no contact with their families.

Iranian Foreign Minister Manouchehr Mottaki said last week that investigators are still questioning the three and that their fate rests with judicial authorities.

Mottaki gave no other details on the case. But his comments suggested that formal charges could still be possible against the Americans, although Iranian President Mahmoud Ahmadinejad said in an interview with The Associated Press last month that he could ask the judiciary to "take a look at the case with maximum leniency."

BEIJING — China will give swine flu vaccinations to thousands of Muslims about to make the annual pilgrimage to Saudi Arabia, state media said, as authorities reported the mainland's third death from the illness.Concerns over the hajj, which attracts about 3 million Muslims every year to the holy cities of Mecca and Medina, have led several countries to impose travel bans over fears the mass gathering could speed the spread of swine flu. Arab health ministers in July banned children, the elderly and those with chronic illnesses from attending this year.All of China's 12,700 Muslims making the pilgrimage this year will be inoculated against swine flu, the official Xinhua News Agency said.China has acted aggressively to detect and contain swine flu cases after being accused of failing to move quickly enough to stop the 2003 outbreak of SARS. Despite earlier measures such as strict quarantines, authorities say the swine flu virus is spreading from cities into the countryside.
