A woman ran for her life after a 20ft long King Cobra reared up at while she was sitting in her living room. Nunta Duangleang, 23, was eating with friends at her house yesterday (Mon) afternoon when the venomous visitor slithered inside and disrupted the meal. The beast leapt up at Nunta from under her sofa, causing chaos as the rubber plantation worker and her pals ran outside in Trang, southern Thailand.
