Magomed Yevloyev, a prominent opposition member and staunch critic of Ingush President Murat Zyazikov, was detained in Ingushetia's main city of Nazran as he stepped off a plane from Moscow, his lawyer and friend Kaloi Akhilgov said by telephone.

He said Yevloyev had flown in business class with Zyazikov, a retired general from the Federal Security Service, and suggested that the two might have quarreled during the flight.
