DIYARBAKIR, Turkey (Reuters) - The seizure of a Turkish Airlines plane ended early on Wednesday when the lone hijacker surrendered, state-run Antolian news agency said. "The hijacker ended the incident by surrendering," Anatolian said. The hijacker, who claimed to have a bomb hidden in a teddy bear, had demanded to be flown to Iran. Officials and witnesses, including passengers, said the incident began when the man seized control late on Tuesday of a domestic Turkish Airlines flight, from Adana to the capital Ankara, and diverted it to southeastern Turkey. The hijacker, a man in his 30s, told crew he had hidden a bomb inside a teddy bear he was carrying. He later released 20 of the 63 passengers and demanded a fresh plane to carry him and several crew to Iran, officials said. Anatolian quoted State Minister Refaittin Sahin as saying the hijacking did not appear to have been carried out on behalf of any group.
