Supporters of ousted Prime Minister Thaksin Shinawatra said they will collect signatures for a petition seeking a royal pardon for the fugitive former leader. Thaksin was convicted in absentia of violating a conflict-of-interest law and sentenced to two years in prison. The campaign was the latest in a series of moves by rival political groups since Thaksin was ousted in a 2006 military coup. (AP Photo/Apichart Weerawong)
