A US rights activist freed in Myanmar is 'thrilled' to be returning home but will need a medical check-up, his fiancee said Thursday after speaking to him. The military-ruled nation released democracy advocate Kyaw Zaw Lwin, also known as Nyi Nyi Aung, who had been arrested in September and later handed a three- year prison term on charges of fraud and forgery. 'I spoke with him and he was very strong, in high spirits and so thrilled to be free,' his fiancee Wa Wa Kyaw, a nurse in the Washington area, told selfnews. But she said that Kyaw Zaw Lwin, 40, who was spending the night in Bangkok as he awaited a flight to the United States, felt pain in one of his legs after his detention.
