(Adds claim of responsibility) ISTANBUL, March 29 (Reuters) - A gas tank exploded in the kitchen of a five-star hotel at a popular Turkish holiday resort on Thursday, killing one person and injuring 11 others, a spokeswoman for the local governor said. The dead man was a hotel worker. A Russian tourist, a Norwegian holidaymaker and nine Turks were being treated in nearby hospitals for minor injuries, she said. The explosion ripped through the hotel kitchen at around 7.30 am (0430 GMT) in the resort of Belek in Antalya province, a popular holiday destination especially for German, British and Russian tourists. The pro-Kurdish Firat news agency said the Kurdistan Liberation Hawks (TAK), a shadowy militant group, had claimed responsibility for the blast. The group, linked to the guerrilla Kurdistan Workers Party (PKK), has claimed to be behind a series of deadly bomb attacks against civilians across Turkey over the last couple of years. The PKK launched a separatist struggle for a Kurdish homeland in southeast Turkey in 1984 and more than 30,000 people have been killed in the conflict.
