Now that Moscow is on board with the thinking that a bomb brought down a Russian passenger jet over Egypt, a newspaper in Russia is reporting that the explosive was in a surprising place: the main passenger cabin. The Kommersant quotes an anonymous investigator who says the device was likely placed under a passenger seat near a window in the tail section, not hidden in the cargo hold, reports Reuters. How it got there remains under investigation, but NBC News reports that Egyptian authorities have detained two workers at the Sharm el-Sheikh airport. So far, no arrests have been made.
