Fr US citizen Pavel Butorin, Thanksgiving is the most important American holiday, but there'll be an empty chair and a gaping absence this Thursday, which his wife will spend in a Russian prison. Alsu Kurmasheva, a US-Russian journalist who like her husband works at the Prague-based, US-funded Radio Free Europe/Radio Liberty (RFE/RL), has been detained for over a month. "Instead, she will be receiving her prison meal through a small window in her prison door," Butorin, a Russian-born US citizen, tells AFP. Kurmasheva was detained after going to Russia in May to attend to her ailing mother. IMAGES AND SOUNDBITES
